Preliminary descriptions of thirty-seven new species of hermit crabs of the genus Eupagurus in the U. S. National Museum

Abstract

Typical species Eupagurus splendescens (Owen). Eupagurus with the manus of the left cbeliped cylindrical. Under this section I have included but three species, the type, E. mertensi Brandt, and E. parvus nov. Subgenus EUPAGURUS. Eupagurus alaskensis. Anterior portion of carapace a little broader than long. Kostral tooth produced to the base of the eye scales; lateral projections much less produced. Eye-stalks short and stout, constricted in the middle. The eye scales taper from the base to a blunt apex; the subtermiual spine is conspicuous from above. The acicles of the antenna? reach the proximal end of the flagella and are three-sided ; sides flat, iridescent. V 18P2 XV ] PROCEEDINGS OF THE NATIONAL MUSEUM. 3 on the outer distal margins and on the inner upper surface of the merus joints of the cbeliped. The lower outer surface of the carpal joints of the ambulatory legs are pointed with red. The propodal joints and dactyls are longitudinally streaked with red. This species is very close to bernhardus, but is easily distinguished by its broader and shorter left hand, by the wide dactyls of the ambulatory legs, by the acicula, and by its pearly iridescence. Alaska. Eupagurus aleuticus. Front with three teeth sharper and a little more prominent than in alaskensis.

Crustacean parasites associated with hermit crabs from the western Mediterranean Sea, with first documentation of egg predation by the burrowing barnacle Trypetesa lampas (Cirripedia: Acrothoracica: Trypetesidae)

“…Distribution and hosts: Mediterranean coast of Spain, in shells occupied by C. erythropus and C. tubularis (new host and locality records); Mediterranean in shells occupied by D. arrosor (Herbst, 1796) (Cuadras & Pereira 1977); Irish Sea, North Sea and Swedish waters in shells occupied by Pagurus bernhardus (Linnaeus, 1758) and P. cuanensis Bell, 1845(e.g. White 1969Jensen & Bender 1973;Reiss et al 2003); east coast of the USA in shells occupied by Pagurus longicarpus Say, 1817 and Pagurus pollicaris Say, 1817(McDermott 2001Williams & McDermott 2004); Gulf of Mexico, Florida in shells occupied by Pagurus impressus (Benedict, 1892) (Spivey 1979).…”

A New Report of Two Species of Pagurid Hermit Crabs (Crustacea: Decapoda: Anomura) from Korea

“…This species is first recorded from Korean waters. It was recorded from the Bering Sea (Benedict, 1892), Sea of Okhotsk (Rathbun, 1904) and from the waters of northen Japan (Komai, 1994). The present study extends the range of geographical distribution of this species southwardly.…”

“…In Korea, 25 species have been reported in this genus. Two species, Pagurus undosus (Benedict, 1892) and Pagurus parvispina are newly recorded as a result of ongoing systematic studies on hermit crabs collected from Korean waters. Brief descriptions and figures of these two species are provided in this paper.…”

New taxonomic and distributional information on hermit crabs (Crustacea: Anomura: Paguroidea) from the Gulf of Mexico, Caribbean Sea, and Atlantic coast of South America

“…More species were documented during the first six decades of the 19 th century (e.g., Say 1817; H. Milne Edwards, 1836Edwards, , 1848Gibbes 1850;Dana 1852;de Saussure 1858;Stimpson 1859Stimpson , 1860Heller 1865), but it was not until the late 1800s to early 1900s, mostly but not exclusively as result of broad deep sea explorations, that a rich hermit crab fauna was discovered in regions encompassing the coast of the eastern United States, Gulf of Mexico, Bermuda, Caribbean Sea, and Brazil. This hermit crab fauna was documented most notably during that period by Smith (1869,1879, 1881a, 1881b, 1883a), A. Milne-Edwards (1880, 1883, Henderson (1888), Ives (1892), Benedict (1892Benedict ( , 1901aBenedict ( , 1901b, Rathbun (1897Rathbun ( , 1900Rathbun ( , 1907Rathbun ( , 1919, , Rankin (1898Rankin ( , 1900, Moreira (1901), Verrill (1908), Bouvier (1918), and Hay & Shore (1918). In the next four decades, several carcinologists studied hermit crabs from various regions of the temperate or tropical northwestern Atlantic, including the southeastern United States to Florida Keys, Bahamas, and some of the Antilles (e.g., Schmitt 1933Schmitt , 1935Schmitt , 1936Wass 1955Wass , 1963Provenzano 1959Provenzano , 1961Provenzano , 1965…”
