from a simple condition similar to that of H. abyssalis. All of the 

 specimens at hand, however, have at least two long setae at that loca- 

 tion and are recognizable as H. excavata, but juveniles have not been 

 captured because of the coarseness of the sorting screens. Both 

 H. excavata and H. ahyssaUs are characterized by the large, apically 

 blunt gland-cone of antenna 2.

Harpiniopsis fulgens J. L. Barnard 



Harpiniopsis fulgens J. L. Barnard, 1960b, p. 332, pis. 67, 68 ; 1966a, p. 85. 



All of these specimens have the long tooth of pleonal epimeron 

 3 shown by Barnard (1960b, pi. 68) . The largest specimen is a female, 

 10.5 mm, from 7229; the specimens of that sample have a slightly 

 narrower article 2 of pereopod 5 than that shoAvn by Barnard (1960b, 

 pi. 67) . Possibly the populations with the long epimeral tooth should 

 be relegated to infraspecific status because their gnathopods are con- 

 siderably larger than those of the type-form. 



This species is very similar to H. simiUs Stephensen (1925) but 

 differs by the presence of spines on the rami of uropods 1 and 2 and 

 the much longer article 6 of pereopod 4.

The third pleonal epimeron differs from the type figures as shown 

 in the accompanying illustration and the second article of the outer 

 ramus of uropod 3 is relatively shorter but all other characters are 

 similar to those of the type.
