44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 28 



tember 6, 1949, i specimen. In 216 feet, 4.3 miles out, October 6, 

 1949, 30 specimens. In 152 feet, 3.5 miles out, October 14, 1949, 

 2 specimens. In 175 feet, 4 miles out, October 14, 1949, 35 specimens. 



The present records are the second of the occurrence of this species, 

 which was described by Gurjanova from the Sea of Japan in 1938. 

 It appears to be fairly abundant in the waters around Point Barrow. 

 Some figures of an Alaskan specimen are here given in order to help 

 establish the identity of the species. 



The lateral angles of the head are produced sharply forward. The 

 lower distal margin of the first joint of the first antenna is produced 

 forward. The lower hind corner of the first three coxal plates is 

 produced into a prominent hook. The lower hind margin of the 

 second joint of the last three peraeopods is obliquely truncate. The 

 telson extends a little beyond the peduncle of the third uropod. The 

 largest specimen in the present collection measures about 10 mm. 

 This species has been taken down to about 125 m.

Material collected. — In no feet, September 9, 1948, i specimen. 

 In 175 feet, 4 miles out, October 4, 1949, i specimen. 



The lateral lobes of the head are rather broadly rounding. The first 

 three coxal plates do not have a hook at the lower hind corner, but 

 only a shallow indentation bearing a setule. The second joint of the 

 last three peraeopods has the hind margin evenly rounding below and 

 not truncate as in Sympleustes uncigera Gurjanova. There are no 

 dorsal teeth. At the outer distal end of the peduncle of uropod i there 

 is a small spine, which is no larger than the spines on the outer margin 

 of the peduncle. The telson extends a little beyond the peduncle of 

 uropod 3. There is no hook or tooth at the lower hind corner of the 

 third metasome segment. 



The present record appears to be the second of the occurrence of 

 this species, which was described from the Kara Sea. It measures 

 about 5 mm., and has been taken at 165 m.
