 B. 6. D. 88. A. 68. 

 Body pyriform, transparent and very delicate ; its height not quite 

 2f in the total, without caudal. The length of the head is one-third of 

 the total, without caudal, and the height rather more. The snout is 

 obtuse and half as long as the eye. Eyes on the left side, their diameter 

 31 in the length of the head ; the lower slightly in advance, and separat- 

 ed from the upper by a downward shelving ridge. Cleft of mouth 

 nearly vertical : the maxilla being 3i to 3f in the length of the head. 

 Minute teeth in a row in each jaw, and in a patch on the vomer. Gill- 

 cleft wide ; opercles thin ; branchiostegal rays prolonged. Gill-rakers 

 distant, lanceolate. Body covered with minute, thin, and very decidu- 

 ous scales. Lateral lino salient : it has a rather shallow curve above the 

 origin of the pectoral, and is continued along the caudal. The dorsal 

 fin commences on the snout ; its longest rays are a little more than half 

 the length of the head, and slightly shorter than the longest anal rays. 

 Interneural and interhaemal spines long. A small median pre-anal 

 spine. The pectoral is more developed on the coloured side, where if 

 laid forward it reaches to the middle of the lower (anterior) eye. 

 Ventrals six-rayed ; the left more expanded than the right. Caudal 

 long and pointed, with 17 simple rays ; its length one-fifth of the total. 

 Colours— left side white, with a few minute black dots. The body is 

 traversed by three narrow black longitudinal lines, one of which is the 

 lateral line, while the others follow respectively the outlines of the 

 tips of the neural and haemal spines ; vortical fins black ; loft pectoral 

 grey at its base and black in its posterior two-thirds ; left ventral black ; 

 prolongation of the left branchiostcgals and membrane black. Total 

 length 31 iucho&. One specimen.
