“…1990. Winterbottom (1982) recorded the range of H. thomaseni as extending from Karachi, Pakistan, to the Bay of Bengal. Material collected since that time extends the range westward to the southeastern coast of Oman at Masirah Island, a scant 600 km east of the collection site of H. coccus.…”

“…The new species differs from H. thomaseni in having usually more dorsal-fin rays (64-68 vs. 58-64), anal-fin rays (52-55 vs. 45-50), pectoral-fin rays (10 vs. 7-9), caudal (5 1-55 vs. 45-49), and total (69-73 vs. 64-68) vertebrae; fewer gill rakers on the lower limb of the first gill arch (5-6 vs. 6-7); and no scales on the cheek, opercle, nape, or above the dorsal lateral line (vs. scales present). The figure of the head pores of H. thomaseni presented by Winterbottom (1982) contains three errors. The uppermost pore labelled as belonging to the preopercular series is, in fact, the intertemporal (and there are thus 7, not 8, preopercular pores).…”

“…The gill membranes are fused to the isthmus and pelvic fins are absent. The presence of a dark, ocellated spot above the anterior and posterior temporal canal pores on the shoulder dorsal to the gill opening used by Winterbottom Halidesmus was revised by Winterbottom (1982), who recognized three species. The genus is unique among congrogadins in having three lateral lines along the body.…”

WINTERBOTTOM, R., and RANDALL, J.E. 1994. Two new species of congrogadins (Teleostei; Pseudochromidae), with range extensions for four other species. Can. J. Zool. 72: [750][751][752][753][754][755][756]. Two specimens of a distinctive new species of the congrogadin genus Haliophis were recently collected off the south coast of Oman. This species differs from its congeners in morphometric and meristic characteristics, as well as in its highly contrasted black and white pattern. It is described and compared with the other two species of Haliophis, and a key to the species is given. A range extension for Haliophis guttatus from Aden to the vicinity of Misrat, Oman, is reported. A new species of Halidesmus is described from 13 specimens from the southern Oman coast. It is related to H. thomaseni (which is here reported to reach as far west as Masirah Island, Oman). The new species differs from H. thomaseni in most meristic values, in the form of the snout crest, and in reduced squamation. A key to the species in the genus is provided. Halimuraena shakai, known from the Kw~zulu coast of South Africa and from a single specimen from Mauritius, is here recorded from the Comoro Islands. Blennodesmus scapularis, known from northwestern and northeastern Australia, is here recorded from the vicinity of Phuket, Thailand. WINTERBOTTOM, R., et RANDALL, J.E. 1994.

Gross Morphology and Evolution of the Mechanoreceptive Lateral-Line System in Teleost Fishes (Part 2 of 2)

The morphology and development of the mechanoreceptive lateral-line system in teleost fishes is reviewed, and the systematic distribution of defined types of lateral-line systems is summarized. The importance of an understanding of ontogeny is stressed and the roles of phylogenetic and developmental constraints in the evolution of the lateral-line system are discussed. Four types of head canal systems are identified on the basis of the relative development of the canals and the orientation of the neuromast receptors contained within them. The distribution of these patterns in the four major teleost clades is analyzed. It is suggested that a branched tubule system associated with the head canals is a primitive teleost character, while widened and reduced head canal patterns are convergent functional specializations in many taxa. The trunk canals are contained in a continuous series of lateral-line scales, and eight trunk canal patterns are described in teleosts. Given the correlation of the systematic distribution of the different trunk canal patterns, ecological habit and body shape, it appears that the trunk canals may function as a hydrodynamic monitor in swimming fishes.

The structure and ontogeny of lateral-line canals in the Rock Prickleback, Xiphister mucosus, were studied using cleared-and-stained specimens, and the distribution and morphology of neuromasts within lateral-line canals were examined using histology. X. mucosus has seven cephalic canals in a pattern that, aside from four branches of the infraorbital canals, is similar to that of most teleostean fishes. Unlike most other teleosts, however, X. mucosus features multiple trunk lateral-line canals. These include a short median posterior extension of the supratemporal canal and three paired, branching canals located on the dorsolateral, mediolateral, and ventrolateral surfaces. The ventrolateral canal (VLC) includes a loop across the ventral surface of the abdomen. All trunk canals, as well as the branches of the infraorbitals, are supported by small, dermal, ring-like ossifications that develop independently from scales. Trunk canals develop asynchronously with the mediodorsal and dorsolateral canals (DLC) developing earliest, followed by the VLC, and, finally, by the mediolateral canal (MLC). Only the mediodorsal and DLC connect to the cephalic sensory canals. Fractal analysis shows that the complexity of the trunk lateral-line canals stabilizes when all trunk canals develop and begin to branch. Histological sections show that neuromasts are present in all cephalic canals and in the DLC and MLC of the trunk. However, no neuromasts were identified in the VLC or its abdominal loop. The VLC cannot, therefore, directly function as a part of the mechanosensory system in X. mucosus. The evolution and functional role of multiple lateral-line canals are discussed.
