CEUSTACEA COLLECTED IN PUGET SOUND, N.A. '279 



spines could be seen, but in another specimen there were 

 7 on both legs. 



Second legs, tarsus 4-jointed. 



Bemaining legs, tarsus 8-jointed. 



Telson, lateral margin with about 24 spines extending 

 the whole length, slightly concave, and not incurved near 

 the tip ; two terminal spines on each apex, the outer 

 twice as long as the inner ; cleft with straight sides armed 

 with about 30 rather long spines. 



Uropods, the inner considerably shorter than the outer, 

 with 4 spines at the proximal end of the inner margin. 



This species is distinguished from H. (Chiromysis) 

 microps (Sars),* H. formosa, S. J. Smith,! and H. nor- 

 vegica, Sarst (the two last species are united by Norman§), 

 by the teeth on the ocular peduncles, the shorter carpus 

 of the first and the different jointing of the remaining 

 legs, and by the entire lateral margins of the telson being 

 armed with spines instead of the distal portion only. 

 The specific name is from o8os, a tooth, and o\p, an eye.
