Ebalia sp. 



A badly mutilated specimen of an Ebalia was obtained at Station 3355 in 

 182 fathoms, — evidently belonging to an undescribed species. The cara- 

 pace, as far as can be determined, is subrhomboidal, tuberculated, and thickly 

 covered with round bead-like granules. The front is truncate; the gastric 

 region roof-shaped, falling off on each side of the median line into the deep 

 depression behind the antero-lateral margins. The antero-lateral border is 

 produced into three lobes, one of which is on the hepatic region and two 

 (larger) on the branchial, the posterior one forming the lateral angle of 

 the carapace ; there is also a prominent tubei'cle on the pterygostomian 

 region. The central part of the branchial region is very prominent and 

 obscurely divided into three secondary prominences made up of an agglom- 

 eration of larger and smaller sized granules. The posterior margin is bi- 

 lobed, each lobe being convex above when the animal is viewed from behind. 

 The buccal area is separated from the antennular fossae by a small epistome. 

 The battered condition of the -specimen (a male) does not admit of a more 

 detailed description.

Carapace very convex from side to side, naked, smooth or nearly so, 

 punctate. Rostrum acute, lightly carinate, the carina extending back for a 

 short distance on the carapace. Superior margin of orbit armed with three 

 acute teeth, the second of which is curved forward ; the anterior tooth is 

 separated from the rostrum by a deep rounded sinus, from the second tooth 

 by an angular notch ; the second tooth is separated from the third by a
