NO. I POINT BARROW AMPHIPODA — SHOEMAKER 63 



proximal lobe (fig. 18, k). Coxal plates overlapping slightly; first 

 plate produced considerably forward below, and all plates furnished 

 with long marginal setae. Length of fully grown male about 14 mm. 



Female. — The female is like the male except that the gnathopods 

 are a little smaller and weaker. Mature females are as large as the 

 males. 



Type. — A male, U.S.N.M. No. 92257, washed ashore at Point Bar- 

 row base, Alaska, August 21, 1949, collected by Geo. E. MacGinitie. 



Beside the Alaskan specimens there are in the U. S. National 

 Museum a specimen of this species taken at Nain, Labrador, August 

 1908; and one at Port Burwell, Labrador, October 1927. 



Protomedeia stephenseni has been taken at Spitzbergen, North 

 Norway, Iceland, East and West Greenland. Many of the localities 

 assigned to this species by Stephensen (1942, pp. 384 and 385) un- 

 doubtedly belong only to P. grandimana. 



Remarks. — The female of P. stephenseni can be distinguished from 

 P. fasciata by the group of long terminal setae on the outer ramus 

 of the third uropod, the latter species having only one long seta and 

 several short terminal spines. P. grandimana has a few long terminal 

 setae, but not a conspicuous brush as in P. stephenseni. 



PODOCEROPSIS LINDAHLII Hansen 



Figure 19, a-g 



Podoceropsis lindahlii Hansen, 1887a, p. 157, pl- 6, fig. 2.— Stebbing, 1906, 

 p. 619. 



Material collected. — In 135 feet of water, 3.1 miles out, March 9, 

 1950, I specimen. 



The specimen described and figured by Hansen appears to have 

 been a female. As this species has not been taken since its discovery 

 in 1887, the single specimen, a male, taken at Point Barrow, is here 

 described and figured. 



Male. — Head about as long as the first two body segments com- 

 bined; lateral lobes produced considerably forward; eye oval and 

 situated in the front of the lateral lobe. Antenna i a little over two- 

 thirds as long as antenna 2, which is about one-half as long as the 

 body. Antenna i, first joint two-thirds as long as the second, and 

 equal in length to the third; second joint one-third longer than third 

 joint; flagellum about two-thirds as long as the peduncle and con- 

 sisting of about 12 joints. Antenna 2, third joint a little over one- 

 third the length of the fourth, which is equal in length to the fifth ; 

 flagellum not quite as long as the fifth peduncular joint, and con- 

 sisting of about 7 joints, the first of which is the longest.
