D. i^. A. ^. L. lat. 28. L. transv. ''-^. 



The height of the body is two-fifths of the total length (the caudal 

 fin not included) ; the snout is as long as the eye ; the width of the 

 infraorbital ring below the orbit is less than one-third of that of the 

 orbit; scales on the cheek of moderate size, in two series. Each 

 jaw with about forty teeth, the anterior ones of moderate length, 

 distinctly compressed ; the middle rays of the dorsal and anal fins 

 and the caudal lobes are more or less produced into filaments. 

 Eeddish-olive (in spirits) : head and base of the soft dorsal and anal 

 dotted with bluish ; dorsal and anal blackish ; caudal and ventral 

 light-brownish. 



Mozambique. 



a. Forty-four lint: long. Mozambique. From Prof. Peters's Col- 

 lection. 



Prof. Peters su^s that this species has during life a coloration 

 very similar to that of Pomacentrus pavo. 



46. Glyphidodon modestus.

The height of the body is contained twice and three-fifths in the 

 total length (without caudal), the length of the head thrice and a 

 half. The diameter of the eye is two-sevenths of the length of the 

 head, equal to the extent of the snout and to the width of the inter- 

 orbital space, which is convex. Infraorbital ring and i^rseopercular 

 limbs naked ; the width of the prseorbital, above the angle of the 

 mouth, is rather less than one-half of that of the orbit. Scales on 

 the cheek small, in three series. Teeth rather narrow, about forty in 

 each jaw. The posterior dorsal spines somewhat longer than the 

 middle, three-fifths of the length of the head. The soft dorsal and 

 anal and the caudal lobes rounded ; caudal scarcely emarginate, its 

 length being rather more than one-fifth of the total. YeUowish- 

 olive on the back, yellowish on the sides ; the outer half of the ver- 

 tical fins greyish, pectoral and ventral white ; a very faint brownish 

 dot superiorly on the axil of the pectoral. 



East Indies. 



a. Forty lines long. Amboyna. Purchased of Mr. Frank. 



b. Half-grown. China Seas. Presented by Vice-Admiral Sir E. 



Belcher, C.B. 

 e. Half-grown. 



I cannot find any other diiference between this species and Gh/- 

 phidodon phaiosoma (Bleek. Verhand. Batav. Genootsch. xxii. Ikli, 

 p. 9), except that the colour of the latter is a uniform brown.
