The form defined as found in the "logger-head sponge," with no 

 special number given, appears to be a different species, judging 

 from the large chela, our plate 34, fig. 3 (their pi. 24, fig. 8), for 

 this chela is remarkably elongated and swollen above proximally, 

 so that the proximal end projects backward over the carpus, which 

 is articulated lower down than usual. The fixed finger or "pollex" 

 is extremely short, much shorter than the dactyl. It is, perhaps, 

 as near that of S. longicarpus of Coutiere as to any of the forms 

 described by him, but does not agree well with it.

Rostrum acute, a little longer and narrower than the ocular 

 lobes, which are triangular and acute or subacute, about as long 

 as broad. (PL 38, fig. i.) Antennules rather stout; articles of 

 the peduncle have proportions about as 2.3 : 1.2 : i (pi. 37, fig. i, a ; 

 pi. 38, fig. i a) ; the inner flagellum has about five or six articles 

 before it branches ; longer branch is about half the length of the 

 outer flagellum; basal spine (stylocerite) reaches about to end of 

 first article, sometimes beyond it. 



The carpocerite is cylindrical, long, slender, usually nearly or 

 quite six times as long as thick (pi. 38, fig. i, b) ; antennal scale 

 or scaphocerite is small, narrow, much shorter than the carpocerite, 

 but may reach the middle of the distal article of the antennule; 

 its spine is strong and much longer, very acute; the basal spine 

 (pi. 37 and 38, fig. i, b) or basicerite is long, acute and reaches to 

 about the distal third of the larger spine; it has a small secondary 

 short spine or angular tooth at its base. 



The palm of the large chela (pi. 39, fig. 4; pi. 38, fig. ic') 

 is oblong-ovate, a little swollen in the middle, and with a small 

 acute dorsal spine at the distal end, above the base of the dactyl; 

 it usually curves down a little. The length of the dactyl is about 

 half that of the palm ; height of palm about one and two-thirds the 

 length. This chela is relatively a little shorter in the female than
