Decapod Crustacea of Bermuda, Part II. 119 



The telson and uropods show but little variation. Some of those 

 in this lot carried eggs. 



This species is easily distinguished from S. minus and most of 

 the other related species, except longlcarpus, by the abruptly 

 narrowed telson, with only five to six terminal plumose hairs, and 

 by the broadly rounded uropods, sharply denticulated on the outer 

 edges distally. The spine of the antennal scale is unusually long 

 and the scale short and narrow. The rostrum and ocular spines 

 are somewhat like those of S. minus, but the rostrum is more spini- 

 form. 



The only species with which it is likely to be confounded is 

 S. longlcarpus Coutiere, which is closely related. The latter has a 

 much more reduced or quite obsolescent antennal scale ; a shorter 

 carpocerite ; more elongated large chela ; the smaller chela longer 

 and with a longer carpus ; outer lamella of uropods has only 

 seven or eight denticles ; and the tip of the telson only four 

 plumose hairs. 



We took this small species many times in 1898, in the "Reach," 

 in 2 to 3 fathoms ; Castle Harbor ; Long Bird Island ; and in 

 Harrington Sound; also in 1901, in several places, and in Dec., 

 1915 abundantly at Grassmere, in sponges. It was previously 

 taken by Mr. G. Brown Goode, Mr. George Hawes, and by Dr. 

 C. H. Merriam. (Yale Mus.) 



Large numbers were taken from a dark brown, cake-shaped, 

 keratose, fibrous sponge, found on the flats at low-tide on the 

 north side of Long Bird Island. It is sometimes associated with 

 S. minus. 



M. Coutiere recorded it from the Gulf of Mexico, 34 fathoms ; 

 Tampa Bay; and Colon; as well as from Bermuda. He also 

 described a variety, "occidentalis," from Lower California. The 

 latter has no antennal scale and has different uropods, and it may 

 well prove to be a distinct species. 



\Ye found large colonies at Grassmere, near Hamilton, in shal- 

 low water, occupying cavities in a large cavernous sponge, dark 

 smoky brown or blackish externally, sulphur yellow within, 

 exterior crust firm. Often a hundred or more were found in one 

 sponge, not mixed with any other species. Many females had 

 green eggs, Dec. 25, 1915, usually not more than 15 to 20. 



Most of these had the body pale pink or deep pink, others light 

 red, the colors due to minute chromatophores on a pale translucent
