.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 th(^, 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 dact} lus does not extend beyond the 

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

 fringed with hairs. 



A number of individuals were taken by Prof. A. E. Verrill and party 

 at Bailey Ba}', Bermudas, in corallines, at low water, and at Harring- 

 ton Sound, in 181>8. Other specimens were collected at the Bermudas 

 in 187f;-77 by Dr. G. B. Goode.

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

 carcinologist.

"This species is so closely allied to iS. oecldentale and ^S'. steJ>hln<fi 

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

 complete description. 



"•The head is shaped as in S. occidentale; the ej^es have the same 

 position. 



■"Antennula' have second and third joints subequal in length; 

 tlagelhun in the male about as long as the sum of the two preceding- 

 joints, with from nine to eleven joints. 



" AntemiiV have their ])asal joints as in -S'. occidentale. 



""First thoracic legs show some important differences in their distal 

 half. In the male the fifth joint is l)elow as nnich produced as in 

 S. accident (di.^ 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 })rotruding })art of tiie process looks therefore much 

 shorter than \\\S. oceldcnttd), in which it is regularly oblong-triangular 

 and (piite free to about tiie articuhition of the hand. The hand is 

 deep(>r than in S. occidentale and has a different shape; it is slightly 

 more than twnce as long as deep, conspicuously deeper at a shorter 

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

 convex than in iS. oceldcntal<\ whil(> the lower margin is considerably 

 convex in its ])roximal and concave at its distal half; the distal process 

 is longer but nuich narrower than in -S'. (>cc!den.t(d<\ bifurcate at the end
