pale maroon in color, had an over-all length of 25.7 cm. Other 

 measurements were as follows : eye to end of body, 14.8 cm. ; across 

 open end of "skirt," 13.5 cm.; width at base of fin (posterior), 6.8 

 cm. ; width of fin, 5.8 cm. ; length of fin, 6.6 cm. ; diameter of siphon, 

 5 mm. ; diameter of eye, 9 mm.; diameter of pupil, 4 mm. 



Three specimens of the squid Gonatus fabricii (Lichtenstein) 

 washed ashore at Point Barrow on October i, 1949. They were 

 spotted with red on a cream background. Measurements (in mm.) 

 of these three specimens taken after preservation are given below. 

 The over-all length is to the end of the short tentacles.

Four individuals of an unidentified balanoglossid, the largest meas- 

 uring 35 mm. in length and 4 mm. in diameter, were taken : three at 

 125 feet and one at no feet (September 15, 1948). 



Phylum TUNICATA 



Class ASCIDIACEA 



Order APLOUSOBRANCHIATA 



Approximately 30 species of tunicates, only about one-fifth of which 

 were compound forms, were collected. Not all the species have been 

 identified. Because of the abundance of certain forms only a small por- 

 tion of those collected could be preserved ; many were examined and 

 when the data were recorded the animals were discarded. The writer 

 is indebted to Dr. Donald P. Abbott for identifying a representative 

 lot of tunicates so that field and laboratory notes could be made. Dr. 

 Abbott will complete the identifications and publish his results later. 



Several colonies of Amaroucium jragile Redikorzev were dredged 

 at 125 feet, and two species of Amaroucium, probably new, were 

 found attached to hydroids and bryozoans at 125 and 140 feet. Sev- 

 eral colonies of ApUdiopsis pannosum (Ritter), completely covered 

 with sand grains, pebbles, and stolons and stems of hydroids, were 

 taken at 125, 130, and no feet. This species is new to the Arctic. 



The most abundant compound species was Didemnum albidum 

 (Verrill), a soft, white encrusting form with stellate spicules in the
