Decapod Crustacea of Bermuda, Part II. 25 



than the granules ; posterior transverse groove deep and con- 

 spicuous. Orbits not far from lateral margins, the space between 

 only one-third more than their diameter. Granulation of the 

 carapace is coarse and somewhat uneven ; the granules being 

 larger over the central and posterior portions than anteriorly. 



The granules are elevated, obtuse-conic or hemispherical, not 

 crowded, many of them with a pit at the summit, each surrounded 

 by a more or less complete circle or cluster of short stiff hairs. 

 On the gastric area there is a large, broad-based, prominent median 

 ridge, divided into a smaller anterior and a larger posterior part, 

 each portion terminating in an anterior, larger subconical, obtuse 

 or bilobed tubercle, with other similar but smaller tubercles and 

 coarse granules around and behind the apex. The larger tubercles 

 mostly have a crater-like pit in the summit. On the cardiac region 

 there is also a somewhat prominent but less elevated area, on which 

 there are tubercles larger than those adjacent; some of these are 

 in pairs, or they may form a triangular group. A few of these 

 larger tubercles are also scattered elsewhere on the carapace, 

 especially on the branchial areas, but do not form clusters there. 



The abdomen is strongly sculptured ; the elevated areas are 

 coarsely granulated and hairy, much like the carapace ; the second 

 to fourth segments have a median, elevated, obtuse ridge, covered 

 with large granules ; the ridge on the fourth is bilobed longitudi- 

 nally. There is a slight ridge on the fifth, also. The lateral 

 marginal lobes are large, angular, that of the 2d segment larger 

 and broader, subacute, about as long as broad, both edges dentate 

 with many small teeth about equal in size to the adjacent granules. 

 These processes, farther back, are similarly but more minutely 

 dentate on the posterior edge, and nearly smooth or minutely 

 crenulate on the anterior edge. 



The telson is broader than long, not much tapered distally, with 

 the distal angles broadly rounded and the distal edge subtruncate. 

 The proximal part is granulated and hairy, like the abdomen, but 

 distally the surface is covered with numerous somewhat divaricate 

 and forked ridges and sulci, becoming very fine near the edges and 

 covered with rows of short hairs. The uropods are very broad, 

 as long as the telson and sculptured in the same way. Under side 

 of bases of legs and sternum are very roughly sculptured, with 

 many angular elevations and deep pits ; one larger acute or pyra- 

 midal elevation is on the sternum, opposite the base of each leg.
