200 BULLETIN OF THE 



Pontophilus occidentalis, sp. nov. 



Allied to P. ahyssi Smith and P. batei} From the former it differs in 

 having a shorter rostrum, larger eyes, and more strongly developed carinse on 

 the carapace. From the latter it also differs in its shorter rostrum armed with 

 two pairs of lateral teeth ; in the presence of a sharp spine on the sternum be- 

 tween the second pair of legs ; in the length of the antennal scale, which in 

 P. occidentalis is equal to the distance from the tip of the rostrum to the car- 

 diac spine ; in the shortness of the second pair of legs, which reach only half 

 way to the distal end of the merus of the first pair ; and in the absence of the 

 spine on the outer margin of the merus of the first pair of legs. 



The eyes are as large as in P. gracilis Smith (much exceeding the rostrum), 

 but they are nearly colorless, and unfaceted, as in P. abyssi and P. batei. 



Length, 73 mm. ; carapace, 21 mm. 



Station 3361. 1471 fathoms. 2 specimens. 



Paracrangon areolata, sp. nov. 



Rostrum long, acute, upturned, inferior margin armed with two spines. A 

 prominent carina extends the length of the carapace in the median dorsal line ; 

 it is armed with four spines, three on the gastric, one (obsolescent) on the 

 cardiac region. Orbit incomplete, bounded externally by a slender spine. Just 

 below the base of the second antenna the antero-lateral angle of the carapace is 

 drawn out into another rather stronger spine. Just behind this, and from a 

 little higher level, a strong, sharp horn is directed outward and forward ; this 

 horn is in continuity with a rounded ridge which runs inward to the external 

 orbital spine. A longitudinal carina on each side of the gastric region, armed 

 with a small spine a little way behind the middle ; from this spine another 

 ridge runs upward and inward, meeting the median carina at the base of the 

 third spine. The branchial regions are traversed by a series of ridges which 



1 Pontophilus gracilis Bate, Rep. Challenger Macrura, p. 487, 1888. This name 

 having been previously employed for another species by Smith (Bull. Mus. Comp. 

 ZoiJl., X. 36, 1882), I have substituted the name Pontophilus batei for P. gracilis of 

 Bate.
