Decapod Crustacea of Bermuda, Part II. 101 



PLATE XLVII, FIGURES 3 3d. (After Coutiere.) 



In this species the superior lateral basal spine of the antennae 

 is not developed. The rostrum is relatively long and slender, 

 decidedly longer and narrower than the orbital spines, which are 

 also elongated and acute, but with broad bases and incurved inner 

 edges. The rostrum extends to or beyond the end of the first 

 antennular segment. 



The telson tapers regularly ; its apex is convex, not very narrow 

 and has a small denticle at each angle. The small chela lacks large 

 dorsal tufts of hairs on the dactylus. The large chela has a small 

 very acute dorsal spine at the distal margin; carpus very short. 

 The two dactyl claws of the ambulatory legs are very unequal in 

 length, not divergent, slightly curved, the outer one much the 

 longer; the proportions about 3:1; the carpal joint has a distal 

 spine above and below ; the propodus is long and has about eight 

 small spines below. The antennal scale is narrow, shorter than 

 the carpocerite, while its spine is longer than the latter. Basal 

 spine of antennules reaches to the proximal third of the second 

 segment. Carpus of the second pair of legs has the first segment 

 long, equal to the other four combined. 



M. Coutiere records this from Bermuda (col. G. Brown Goode). 

 It was also taken there by our parties, several times, in 1898 and 

 1901. 



It ranges from off Beaufort, North Carolina, in 13 to 16 

 fathoms, through the West Indies to Yucatan, and to Bahia, 

 Brazil, and from low tide to 56 fathoms (Coutiere). It is a very 

 common species in dredgings. Also known from Hawaiian Is. 

 and Lower California (var. brevispinis} ; and Gulf of California, 

 var. me. vie a mis (t. Coutiere). 



It is quite probable that this species was Say's original Alphcus 

 minus, for it agrees best with his description. Say stated that in 

 his species the rostral spine was longer and more acute than the 

 orbital spines, which were conical at base. This is the case in the 

 present species, which is also a common species on our southern 

 coasts (Cape Hatteras to Florida), where Say obtained his speci- 

 mens. Doubtless Say subsequently referred all the related species 

 of SynalpJicus that he obtained to S. minus, as Kingsley and others 

 have done, much more recently. Hence the two specimens men- 

 tioned by Coutiere, now in the British Museum, and sent by Say,
