Parapasiphae cristata, sp. nov. 



(Plate V, Fig. 3.) 



Female. — This species, wbicb is represented by a single specimen 

 (7021), is very closely allied to the last. The dorsal crest of the cara- 

 pax, however, is not truncated nor sulcated in front, but evenly arcu- 

 ated longitudinally, and very sharp to the tip of th^ acute rostrum, 

 which is slightly longer than in P. sulcatifrons. The eyes are very 

 mucli smaller, their diameter being less than a third the length of the 

 stalk, while in P. snlcatifrons the diameter is nearly half the length of 

 the stalk. The eye-stalks themselves are fully as broad as in P. sid- 

 catifrons, expanded at the distal end inside the eye, and terminating 

 in a prominent, curved, and conical tubercle, which projects much iu 

 advance of the eye. The fourth somite of the pleon has a slight dorsal 

 carina back of the middle, and the posterior margin projects dorsally 

 over the fifth somite in a broad angular prominence, not a narrow tri- 

 angular tooth as in P. sulcaiifrons. The fifth somite is rounded above 

 and not sulcated.
