REGAN—MARINE FISHES. 245 
orbital width. Premaxillaries with a double notch anteriorly; maxillary extending 
beyond the vertical from posterior edge of eye; distance from tip of snout to end of 
maxillary 2 the length of head; least distance between eye and maxillary 2 the diameter 
of eye; preopercular spine of moderate length; 10 gill-rakers on the lower part of the 
anterior arch. Dorsal V, 119; second spine 2 the length of head; distance between 
origins of dorsals nearly 3 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 the length of head ; ventrals $ or § 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 mum. in total length, collected and presented to the British 
Museum by Dr. J. D. F. Gilchrist. 
Champsodon arafurensis, sp. 0. 
Depth of body about 5 in the length, length of head 33 to 34. Snout 14 to 14 as 
long as eye, the diameter of which is 44 to 5 in the length of head and greater than the 
interorbital width. Praemaxillaries with a double notch anteriorly ; maxillary extending 
beyond the vertical from posterior edge of eye; distance from tip of snout to end of 
maxillary 2 the length of head; least distance between eye and maxillary less than the 
diameter of eye; przopercular spine of moderate length; 9 to 11 gill-rakers on the 
lower part of the anterior arch. Dorsal [V—V, I 18-19; second spine a little more than 
3 the length of head; distance between origins of dorsals about 2 the distance from tip 
of snout to origin of spinous dorsal. Anal I 17; origin nearly equidistant 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 the ‘ Challenger’ collection. 
This species seems to be nearest to the one figured by Alcock (Ill. Zool. ‘ Investigator,’ 
pl. xxvii. fig. 5), and may be the same. 
Champsodon omanensis, sp.u. (Plate 27. fig. 1.) 
Depth of body about 5 in the length, length of head 3} to 3g. Snout 1; to 14 as long 
as eye, the diameter of which is 5 to 54 in the length of head and a little greater than 
the interorbital width. Premaxillaries with a double notch anteriorly ; maxillary 
extending beyond the vertical from the posterior edge of eye; distance from tip of snout 
to extremity of maxillary 3 the length of head; least distance between eye and maxillary 
nearly equal to the diameter of eye; preopercular spine of moderate length; 9 or 10 
gill-rakers on the lower part of anterior arch. Dorsal (IV) V, 1 19 (20); second spine 
a little more than } the length of head; distance between origins of dorsals } or more 
than 2 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 2 the length of head; ventral 
2 to 3 the length of head, nearly reaching the origin of anal in the young. Silvery;
