Ebalia sp. 
A badly mutilated specimen of an Zaha 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 tubercle 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 fosse 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
