1949, was duller in appearance and was without the transverse bands. 

 Two females had parasitic copepods in their marsupiums. 



Three species of Orchomenella, difficult to distinguish after pres- 

 ervation, could undoubtedly be identified in life by eye color. 

 O. groenlandica, a small white amphipod with large, oval, black eyes, 

 was taken sparingly. 0. pinguis (Boeck), a small, white amphipod 

 with red eyes, was abundant. An ovigerous female with pale orchid 

 eggs was taken through the ice on January 27, 1950, at 37 feet. O. 

 minuta (Kroyer) was taken at Eluitkak Pass and at depths of 80, 120, 

 135, 152, and 741 feet. All are new to the western Arctic. 



Socarnes bidenticulafus (Bate) was dredged from 175 to 453 feet. 

 A female from 453 feet was carrying eggs in a medium-early stage 

 of development and one from 175 feet was carrying young embryos. 

 Ovigerous females were taken in east Greenland (Stephensen, 1944) 

 from July 30 to August 18, 1933, down to about 95 feet. In life this 

 species is a beautiful mixture of maroon and white, with black eyes. 



A single ovigerous female Tryphosa triangida Stephensen was taken 

 from a fish trap at a depth of 33 feet on January 27, 1950. It was 

 pale flesh color, with translucent white appendages. The eggs were a 

 bright maroon. 



A specimen of Stegocephalns in flatus Kroyer was taken at 138 feet 

 and an ovigerous female at 130 feet (August 9, 1949). The latter 

 was tan on a whitish background with an olive-green cast. 



A female Stegocephalopsis ampulla (Phipps) 39 mm. long and with 

 a marsupium was taken at 125 feet. This large amphipod is cream- 

 colored, with a dark dot at the lower edge of each thoracic seginent. 

 Although rather widely distributed in the Arctic, apparently it is not 

 abundant, for it was found only once at west Greenland and three 

 times in Baffin Bay (Stephensen, 1944). 



Two specimens of Ampelisca eschrictii Kroyer, including a female 

 37 mm. long with ovaries full of well-developed eggs, were found 

 (August 21, 1948). This species is white, with orange-red and dull- 

 orange markings, four maroon eyes, and a reddish mouth region. 



Ampelisca hirulai Briiggen was collected from 80 to 216 feet. A 

 female from 216 feet was carrying 14 or 15 eggs about 0.8 mm. in 

 diameter that were in early stages of development. 



Byblis gaimardii (Kroyer), a common and conspicuous amphipod, 

 was taken from depths of 80 to 420 feet. Pinkish or pale-salmon 

 color, with both black and chalk-white pigment "stars" on the head 

 region of the carapace and white pigment stars on the terminal half 

 of the first ostegites, and with four red eye spots (that turn black 

 in preservative), it is easily distinguished in the field. The eggs,
