BRACHAILURUS gen. nov. 
Form rather short and stout, the distal region of the 
tail scarcely elevated above the dorsal plane. Head 
moderate and but little depressed, with rather short, 
broadly rounded snout. Nasal valve folded, with a pro- 
minent cirrus. Mouth inferior, transverse, of moderate 
size, nearer to the eye than to the tip of the snout, with 
well developed labial grooves, which are not continuous 
across the symphysis of the lower jaw, behind which is a 
conspicuous longitudinal groove. Teeth similar in both 
jaws, arranged in many series, small, and tricuspid. Eyes 
small, elongate-oval, with horizontal pupil ; spiracles large, 
below and behind the eye. Posterior gill-sht largest, rather 
nearer to the fourth than the remaining pairs are to one 
another, the three last slits above the base of the pectoral 
fin. Tail a little longer than the head and trunk. First 
dorsal fin originating above the base of the ventrals, and 
subequal in size to the second ; anal fin low, close to the 
caudal: caudal fin with the upper flap feebly, the lower 
moderately developed and notched near the tip; a slight 
notch between the lobes: pectoral and ventral fins large. 
Skin covered with minute, smooth, lozenge-shaped scales 
Ovoviviparous. paxvs short ; déAovpos, a cat). 
Small ground sharks from the coast of southern Queens- 
land, forming a connecting link between the oviparous 
Hemiscylliine and the ovoviviparous Orectolobine. Type 
Brachelurus colcloughi. (v. infra, p. 4). 
Waite’s family Hemiscylliide, characterized “ mainly - 
by having the anal fin behind the second dorsal and in 
being ovoviviparous’”’* will have to lapse, owing to my 
announcement of the oviparity of Chiloscyllium}, which 
necessitates a rearrangement of the scyllioid sharks, of
