anal 16 mm., and the head 16 mm. The orbit is 5 mm. 

 and the snout 3 mm. It has iii/23 dorsal and iii/14 anal 

 rays, and is a species of Pseudochromis. A sketch of this 

 specimen, together with some notes made at the Queens- 

 laud Museum, enable me to identify the example here 

 described and figured as Pseudochromis purpurascens.

D.iii/26; A.iii/14; P.18; V.i/5; C.17. L. lat. 36/6, 

 1. tr. 1|/14; 41 rows of scales between the origin of the 

 lateral line and the hypural joint. 



Depth (14 mm.) 3-4 in the length to the hypural 

 joint (48) ;-head (15) 3-2 in the same. Eye (4) longer 

 than the snout (3-5), 3-7 in the head; interocular space 

 (2-3) 1-7 in the eye. Pectoral fin (9) 1-6, ventral (10) 

 1-5, and caudal (12) 1-2 in the head. Nineteenth dorsal 

 ray (8) and depth of caudal peduncle (8) 1-8 in the head. 



Body compressed and oblong, the upper profile a 

 little more convex than the lower ; snout very obtuse. 

 Series of minute pores encircle the eye, cross the nape, 

 and extend around the preorbital bone and mandible: 

 they are prominent on the preoperculurn, and associated 

 with short tubes which open on the extreme margin of 

 the bone and form several angles. Anterior nostril in a 

 short tube, the posterior a simple opening near the eye. 

 Maxillary reaching backward to below the middle of the 

 eye. Head scales cycloid, deeply imbedded in the skin 

 and inconspicuous, especially on the nape; they are 

 arranged in five or six rows on the cheeks. Opercular 

 bone armed with four or five flat teeth on its postero- 

 superior angle. 



Upper jaw with several pairs of curved canines 

 anteriorly, and an inner band of minute teeth ; this 

 becomes very narrow on each side, where also there is 

 an outer row of somewhat stronger conical teeth. Man- 

 dible with several pairs of canines anteriorly, and one 

 laterally; an inner baud of minute teeth in front, and a
