AKT. 8 CRUSTACEANS FROM WESTERN ATLANTIC TATTERSALL 



27 



Remarks. — This species has a distribution in the area explored 

 very similar to that of S. suhmii. It is, however, rather more abun- 

 dant than the latter and appears to have its maximum of abundance 

 in somewhat deeper water. It occurred in only 4 out of 46 hauls 

 made at less than 200 meters, but in 17 out of 23 hauls between 200 

 and 1,800 meters. It is most abundant between 200 and 500 meters.

 Occurrence 



RemarJcs. — The distribution of this species in the tropical oceanic 

 area is practically the same as that of S. longicorne. It was not taken 

 at depths of less than 100 meters and appears to be most abundant 

 between 100 and 500 meters.
