spine, almost touching the carpal process. The ischium is antero- 

 distally produced in a short process. 



The other legs are simple, bi-unguiculate. 



In the female the carpus of the first pair of legs is not produced in 

 as long a process as in the male. The propodus is shorter than in the 

 male, more triangular in shape, denticulate on its distal margin, with 

 a long, acute, digital spine. The dactylus does not extend beyond the 

 digital spine. The ischium is antero- distal ly produced in a process 

 fringed with hairs. 



A number of individuals were taken by Prof. A. E. Verrill and part}' 

 at Bailey Bay, Bermudas, in corallines, at low water, and at Harring- 

 ton Sound, in 1898. Other specimens were collected at the Bermudas 

 in 1876-77 by Dr. G. B. Goode. 



Type specimens from Harrington Sound in Peabody Museum, Yale 

 University. Cat. No. 3209. 



This species is named for Rev. T. R. R. Stebbing, the English 

 carcinologist.

Locality. West Indies. Found on corals in deep water. 



"This species is so closely allied to S. occidentals and 8. stebbingi 

 that it is preferable to point out the differences instead of giving a 

 complete description. 



"The head is shaped as in S. occidentale; the eyes have the same 

 position . 



"Antennula? have second and third joints subequal in length; 

 flagellum in the male about as long as the sum of the two preceding 

 joints, with from nine to eleven joints. 



"Antenna? have their basal joints as in S. occidentals. 



"First thoracic legs show some important differences in their distal 

 half. In the male the fifth joint is below as much produced as in 

 S. occidentals, but the process is differently shaped; its proximal half 

 is expanded above and excavated on the upper half of the outer side 

 in order to receive the proximal lower part of the hand; the oblong- 

 triangular, freely protruding part of the process looks therefore much 

 shorter than in$. occidentals, in which it is regular!} 7 oblong-triangular 

 and quite free to about the articulation of the hand. The hand is 

 deeper than in S. occidentals and has a different shape; it is slightly 

 more than twice as long as deep, conspicuous!}- deeper at a shorter 

 distance from the base than at the distal end; the upper margin is less 

 convex than in S. occidentals, while the lower margin is considerably 

 convex in its proximal and concave at its distal half; the distal process 

 is longer but much narrower than in 8. occidentals, bifurcate at the end
