orbital width. Prsemaxillaries with a double notch anteriorly ; maxillary extending 

 beyond the vertical from posterior edge of eye ; distance from tip of snout to end of 

 maxillary f the length of head ; least distance between eye and maxillary f the diameter 

 of eye ; prseopercular spine of moderate length ; 10 gill-rakers on the lower part of the 

 anterior arch. Dorsal V, I 19 ; second spine f the length of head ; distance between 

 origins of dorsals nearly J the distance from tip of snout to origin of spinous dorsal. 

 Anal I 17 ; origin equidistant from tip of snout and base of caudal or nearer the former. 

 Pectoral f the length of head ; ventrals f or f the length of head, in the young reaching 

 the origin of anal. A series of dark spots or vertical bars on the side ; fins yellow, the 

 caudal dark at the base. 



South Coast of Cape Colony, 30 to 35 fathoms. 



Four specimens, 40 to 75 mm. in total length, collected and presented to the British 

 Museum by Dr. J. D. F. Gilchrist, 



Champsodon arafurensis, sp. n. 



Depth of body about 5 in the length, length of head 3^ to 3|. Snout 1| to Ih as 

 long as eye, the diameter of which is 4J to 5 in the length of head and greater than the 

 interorbital width. Praemaxillaries witli a double notch anteriorly ; maxillary extending 

 beyond the vertical from posterior edge of eye ; distance from tip of snout to end of 

 maxillary f the length of head ; least distance between eye and maxillary less than the 

 diameter of eye ; prseopercular spine of moderate length ; 9 to 11 gill-rakers on the 

 lower part of the anterior arch. Dorsal IV- V, I 18-19 ; second spine a little more than 

 ^ the length of head ; distance between origins of dorsals about f the distance from tip 

 of snout to origin of spinous dorsal. Anal I 17 ; origin nearly equ.idistant from tip of 

 snout and base of caudal. Ventrals a little shorter than the head, extending to the 

 origin of anal. Silvery ; back darker ; upper parts of spinous dorsal sometimes 

 blackish. 



Arafura Sea and Ki Islands, 129 fathoms. 



Three specimens, 50 to 75 mm. in total length, from tlie ' Challenger ' collection. 



This species seems to be nearest to the one figured by Alcock (III. Zool. ' Investigator,' 

 pi. xxviii. fig. 5), and may be the same. 



Champsodon omanensis, sp. n. (Plate 27. fig. 1.) 



Depth of body about 5 in the length, length of head 3^^ to 3^. Snout 1| to 1^ as long 

 as eye, the diameter of which is 5 to 5J in the length of head and a little greater than 

 the interorbital width. Praemaxillaries with a double notch anteriorly ; maxillary 

 extending beyond the vertical from the posterior edge of eye ; distance from tip of snout 

 to extrenaity of maxillary f the length of head ; least liistance between eye and maxillary 

 nearly equal to the diameter of eye ; prteopercular spine of moderate length ; 9 or 10 

 gill-rakers on the lower part of anterior arch. Dorsal (IV) V, I 19 (20) ; second spine 

 a little more than ^ the length of head ; distance between origins of dorsals f or mora 

 than f the distance from tip of snout to origin of first dorsal. Anal I 17 ; origin a little 

 nearer to base of caudal than to tip of snout. Pectoral f the length of head ; ventral 

 I to f the length of head, nearly reaching the origin of anal in the young. Silvery ;
