This fish is very closely allied to P. twpemosoma, Bleeker, or Lepidozygus ta^emosoma, Giintlier. 

 Habitat. — Madras, to 5 inches in length.

Length of head 4|, of caudal 4f , height of body Sf in the total length, ^yes— diameter 3 J in length of 

 head, 1 diameter from end of snout, and IJ apart. Preorbital entire, Suborbital ring of bones below the eye 

 serrated, as is also the hind edge of preopercle. The greatest depth of the preorbital nearly equals the diameter 

 of the eye. Colours — dark oUve, with bluish spots on the cheeks : a curved blue line below the eye, and a broad 

 vertical yellowish band underneath the last dorsal spines : sometimes a black spot on the base of the last few 

 dorsal rays, and a round one edged white at the base of the pectoral. 



Habitat. — ^Andamans to the Malay Archipelago. The specimen figured (life-size) was brought from the 

 Nicobars by the late Dr. Stoliczka.

' Length of head 3J to 3f , of caudal 4J, height of body 2| in the total length. Byes — diameter from 

 3 to 85 in the length of head, 1 diameter from end of snout, and also apart. Preorbital in the adult nearly as 

 deep as long, and equal to the diameter of the eye : in the immature its depth is not nearly as great. The hind 

 edge of the preorbital, the suborbital ring, and the posterior margin of the preopercle serrated. ThemaxiUa 

 reaches to below the hind nostril. Fins — dorsal spines moderately strong, subequal in height but lower than the 

 soft dorsal which is pointed. Caudal emarginate. Lateral-line — the tubes cease below the last dorsal spine. 

 Golowrs — grayish-brown, head with irregular bluish- white dots and one on each scale of the body. A black 

 spot, margined anteriorly and superiorly with white, exists across the base of the last six dorsal rays, and is 

 usually also continued on to the back of the free portion of the tail behind the base of the dorsal fin. 

 Occasionally a dark spot in the axil of the pectoral fin. 



In Forster's Desc. Anim. (Lichtenstein Ed.) p. 227, Ghoetodon lividus, Forst. and Bl. Schn, is said to be 

 identical with Pomacentrus pv/nctatus. 



Habitat. — Red Sea, Mauritius to the Andamans, Nicobars and Malay Archipelago. The specimen figured 

 (life-size) is from the Andamans.

 B. V, D. ^3^, P. 17, V. 1/5, A. ^?t^, C. 17, L. 1. 28, L. tr. 3i/10*. 



Length of head 3f , of caudal 6, height of body 2| in the total length. Eyes — diameter 3 to 35 in length 

 of head, 1 diameter from end of snout, and also apart. Suborbital ring of bones rough, scarcely serrated,* 

 preopercle very finely serrated or even entire : preorbital scaleless, its greatest depth equal to half the diameter 

 of the eye. Maxilla reaches to nearly below the front edge of the eye. Lips very large, thick, covered with 

 papillss, and reflected all round the mouth. Teeth — minute, compressed. Fi/ms — dorsal spines of moderate ■ 

 strength, of about equal height, not equalling the soft dorsal ' which is pointed. Ventral reaches the anal. 

 Upper lobe of caudal usually slightly the longer. Lateral-line — the tubular portion ceases under the commence- 

 ment of the soft dorsal fin. Colours — brown, lightest on the chest and lower surface of the head : fins black. 

 Blue spots on some of the scales of the head, and usually one on the centre of each scale in the row above the 

 lateral-hue. 



This species is distinguished from any others recorded from India by its enormously developed lips. 



Habitat. — ^Andamans and Mcobars, to 3| inches in length. 



Genus, 6 — Gltphidodon, (Lacepede), Cuvier. 



Fuschistodus, DiscMstodus, Hypsipops, Pomatoprion, Microspathodon, GUI. 



BramcUostegals five or six : pseudobraMohice. Body short, compressed. Cleft of mouth small. Opercles 

 entire.^ Teeth compressed and im, a single row, sometimes the alternate ones being simila/r. A single dorsal fin with 

 the spines rather more or less, or equal in number to the rays : anal with two spines. Scales of moderate size. The 

 tubular portion of the lateral-line ceases below the end of the dorsal fin, but is continued in the form of minute circular 

 orifices. Air-vessel present. Pyloric appendages few. 



* This fish in some specimens (always perhaps in the young) has no serrations in the bones' of the head, in others the snh-i 

 orbital ring la roughened and the preopercle is finely serrated.
