Apogon notata, sp. nov. 



B. vii. D. Gj|. r. 13. V. 1/5. A. 2/16. C. 17. L. r. 20. 



Length of specimens up to 3 inches. 



Length of head ,4,-, of pectoral ^, of base of first dorsal i, of base 

 of anal 5, of caudal ^ of the total length. Height of head ^, of body ^, 

 of first dorsal -^^, of second dorsal I, of ventral g, of anal g of the 

 total length. 



Eyes circular, diameter ^ of length of head ; g a diameter apart, 

 ■| of a diameter from end of snout. 



Body rather elongated and compressed. Mouth moderately wide, 

 lower jaw slightly the longest ; the posterior extremity of the maxilla 

 reaches to beneath the centre of the orbit. No spines around the 

 margin of the orbit. Angle of proeoperculum rather produced and 

 rounded, lower limb with a single line of serrations just above the 

 lower edge of the horizontal limb, which, however, is entire. Oper- 

 culum without a spine, but ending in a soft prolongation. 



Teeth villiform, in numerous closely set rows in both jaws, but 

 smallest in the upper ; a row of rather larger teeth in the palatines, 

 and a small patch on the vomer. 



Fins. First dorsal with very weak spines, the third of which is the 

 longest, whilst the interspinous membrane is rather deeply emargi- 

 nate. A short interspace exists between the two dorsal fins ; the 

 second dorsal highest anteriorly. First anal spine nearly half the 

 length of the second, which is two-thirds that of the first ray. 



Scales deciduous. 



Lateral line nearly straight. 



Colours. White, with a ]nnk tinge along the abdomen and on the 

 fins. A rather large black finger-mark on the lateral line at the root 

 of the caudal fin. Opercles silvery. 



In Malabar I never procured an Apogon, but the Ambassis abounds. 

 In Madras, on the contrary, the former appear to be numerous, 

 whilst the latter are comparatively rare. 



Pristipoma neilli, sp. nov.

 L. tr. 10/15. 



Length of specimen 7 inches. 



Length of head |, of pectoral \, of base of dorsal spines rather 

 more than \, of base of dorsal rays i, of base of anal i, of caudal ^ 

 of the total length. Height of head -\, of body rather more than ^, 

 of dorsal spines \, of dorsal rays ^, of ventral i, of anal spines -f^, 

 of anal rays 1 of the total length. 



Eyes. Upper margin near the profile, diameter g of length of 

 head; | of a diameter apart, nearly 1 diameter from end of snout. 



Body ovoid, moderately compressed. A rather considerable rise 

 from the snout to the base of the dorsal fin. 



Jaws of about equal length, a deep groove under the symphysis of 

 the lower jaw, with a small facet 011 either side of its anterior portion.
