Forty-four species of fishes are recorded, belonging to twenty-one families. Twenty-riine are rnarine {orms, two are anadromous, and thirteen'are predom.inantly or entirely freshwater forms. Seventeen are new records for Ungava Bay, and a few are new for the rvhole of the Canadian Eastern Arctic. The marine piscine fauna is shown to be in the nlain subarctic, containing such arcticsubarctic forms as Saloeli,nu,s alTtinus, Reinhardtius hippoglossoidbs, Ggmnocanthus tdcuspis, lcelus bi.cormis, Asuidophoroides olriki, Lumnemts fubricii, etc., and subarctic-boreal species such as Salmo salar, Gadus callarias, Sebastes marinus, Liparis atl.anticus and Mallot1ts aill.osus. More strictly arctic species in the fauna are Boreogadus srilda, Triglops ngbekni' and Oncocottns quadricomis; there are two Atlantic boreal species recorded, Paralepis rissoi kriigeri anld Larnpaqgctus crocod.ilus, and the remainder are fishes of r.r'ide north-south range, found in all three zones (aictic, subarctic, boreal), such as Sornniosus microcephalus hl.gctophum gl'aciale, Ammod.ytes d,ubius, T'ri,glops pir-tgeli, Eum.icrotremus spi,nosus, Liparis tunicatus, Lumpemn maculatus, Lu codes r etiatlatus.

The young of the white shrimp, Penaeus seti]erus (Linnaeus), grow up in estuarine waters the salinity of which is governed by rainfall. The Texas shrimp fishery was well started by 1927. From that time until •936, catches were relatively low. The fishery underwent a period of growth and high-level catches have been obtained from 1937 to the present. During that period the annual catch in pounds of any one year shows a correlation coefficient of 0.883 with the State's average rainfall of the same year and 2 previous years. Essentially, there were 2 blocks of dry years with a period of wet years between, during which the catches were low and high, respectively. Decline of the white shrimp catch has been sharp with the recent drouth, but it is expected to rise when the drouth breaks. Whether the correlation is directly with salinity per se or some unknown factor governed by salinity is not known.

Chronic transplant rejection with diminished renal function and development of serious hypertension resistant to treatment occurred in a 36-year-old patient 3 years after kidney transplantation. Symptoms of vascular obstruction resulted in detection of advanced stenosis of the external iliac artery prior to branching of the transplant artery. Obstruction disappeared after percutaneous transluminal dilatation of the stenosis, renal function improved, and blood pressure returned to normal with reduced medication.
