well-developed muciferous cavities : its length (excluding a membra- 

 nous extension backwai-ds of tlie operculum) 3| in tlie total. The lower- 

 jaw is strongly prominent, with a strong sub-symphysial knob, which 

 forms the tip of the snout. Preoperculum with a double border : the 

 outer border recurved at its angle and strongly serrated there and along 

 its horizontal limb ; the inner with three small spines at its angle. 

 Operculum naked, with two weak spines ; its angle has a membranous 

 extension backwards to the level of the anterior third of the pectoral flu. 

 Snout, with the projecting lower jaw, as long as the eye, which is 3|- 

 iu the head as above limited. luterorbital space narrower than the eye, 

 nearly flat from side to side, and marked with obliquely converging linea 

 which bound the muciferous cavities of the skull. Nostrils large. 



Cleft of mouth very oblique, and wide : the mandibles emarginato 

 on either side of the symphysis. Villiform teeth in promaxillfB, vomer, 

 palatines, and front of mandibles : in addition, a pair of strong fang-liko 

 canines anteriorly in the upper jaw, and four large and five or six small 

 upstanding recurved teeth on each side of the lower, and a single similar 

 tooth of medium size near the symphysis. Gill-cleft wide : gill-rakers 

 close-set, numerous, and nearly half as long as the eye. Scales exces- 

 sively deciduous : one from the abdomen is ^ of an inch iu diameter, 

 with a vertical, crenated posterior edge. The dorsal fins are separated 

 by an interspace equal to three-fourths the length of the eye : the 

 spinous is considerably the higher : the 1st spine is small, the 3rd is 

 the longest and is equal to two-thirds of the body height, the 4th is 

 nearly as long. The 1st anal spine is short, the 2ad as long as the 

 eye. Caudal forked almost to its base, forming two distinct lobes. 

 Pectoral delicate; its length equals the distance from the tip of the 

 snout to the anterior pre-opercular edge. Ventral long, reaching two- 

 thirds of the distance to the anal : its spine is long, having its outer 

 edge sot-close with small uniform recurved spines. Colours m life, 

 transparent light brown suffused with the pink reflex of the great 

 vessels : opercular and visceral regions like burmshed silver. 



Total length SfV inches. The intestine is long and much coiled ; 

 and there are five very large pyloric cffica. 



Taken in 68 fathoms 16 miles east of the Devi mouth of the Maha- 

 naddi delta, k similar sized female specimen with ripe ovaries was 

 taken in G5 fathoms (temperature 62" Fahr.) in Lat. 20° 18 N., Long.

Family ScoBPJiNiDJ!. 

 Two species of Schasles were obtained in loss depths than the above. 

 One of them appears to be Sehades serrulatus, (Richardson); and I 

 venture to describe it under that name.
