Decapod Crustacea of Bermuda, Part 11. 105 



styliform distally and translucent at the tip. A slight dorsal carina 

 extends back from rostrum. The rostrum connects below with 

 ocular projections by a simple, thin, slightly incurved margin. 

 There is a strong bulge over the eyes. 



The basal antennular spine is rather long, slender, acute, reach- 

 ing the middle of the second article, but not to middle of scapho- 

 cerite spine ; it has a small acute secondary spine at its base. The 

 articles of the antennules are stout and somewhat expanded at 

 their distal ends ; outer flagellum branches at tenth annulus. 

 Carpocerite is somewhat fusiform, with the middle a little swollen, 

 length 4.5 times the width (pi. 34, 2b) ; its spine is equally long, 

 strong, acute ; it reaches end of antennular peduncle ; its scale is 

 narrow, shorter than the spine. 



Third maxilliped (fig. 211") is long and not very stout; its third 

 article is enlarged distally, 4.5 longer than wide, and about as long 

 as the carpocerite ; the penultimate article is longer than wide, one 

 fourth the preceding ; last article slender, tapered, six times longer 

 than wide ; tips oblique, with about six acute spines and a tuft 

 of long plain hairs ; about seven transverse rows of hairs partly 

 feathered on one side ; exopod as long as the adjacent article, with 

 a terminal tuft of numerous long hairs. 



Larger chela is smooth, oblong-elliptical, a little swollen proxi- 

 mally; thumb rather large, pointed, shorter than dactyl, deeply 

 cut away on the inner side, where there is a deep canaliculate notch, 

 above which the margin is very oblique, with three raised tubercles, 

 the lower one largest; dorsal articular margin with three small 

 denticles, the inner dorsal with an acute tip, the others obtuse; 

 outer articular margin nearly transverse, with two rounded denti- 

 cular tubercles, above a narrow notch at the angle; the cutting 

 margin, beyond the notch, has a large, prominent rounded lobe. , 

 Dactyl is large, compressed, strongly arched externally; inner 

 edge is not much incurved, but has two small lobes on the outer 

 edge, and a distinct inner tooth distally (pi. 23, fig. 3). The form 

 of this chela differs in the sexes ; those of the male (pi. 33, figs. 5, 

 50) are more swollen and the dactyl is longer than half the palm. 

 Those of the female (figs. 4, 40) are narrower, more oblong, and 

 the dactyl is equal to or less than half the length of the palm. 



The smaller chela (fig. 2/') is narrow elliptical, with both 

 margins of the palm slightly convex, fingers are acute, or minutely 

 two-toothed ; dactyl is evenly arched and bears two or three tufts
