Brachelurus, Ogilby, Proc. Roy. Soc. Queensl., xxi, 1907, p. 3, 
(nec Brachelurus, Ogilby, loc. cit., xx, 1906, p. 27). 
Heteroscyllium, Regan, Ann. Mag. Nat. Hist., ii, (8) 1908, p. 455. 
As shown on page 280, the name Brachcelurus cannot be 
used for the following species, and Heteroscyllium has 
therefore been proposed in its stead. 
Body short and stout, not depressed, becoming gradually 
more compressed posteriorly, the distal portion of the tail 
slightly elevated above the axial plane. Scales extremely 
small and feebly unicarinate; lateral line conspicuous. 
Head rather small and narrow, with moderate rounded 
snout, and without lateral dermal lobes. Nasal valve folded, 
with a well developed free cirrus. Mouth inferior, trans- 
verse, of moderate size, below the anterior portion of the 
eye; lips not thick nor fringed within; labial grooves well 
developed, not continuous across the symphysis of the lower 
jaw, behind which is a conspicuous longitudinal groove. 
Teeth in both jaws small and tricuspid, arranged in many 
series. Spiracles large and subcircular, below and wholly 
behind the eye, surrounded by a prominent rim. Gill-slits 
moderate, increasing in size from the front; three above 
the pectoral. Tail alittle longer than the head and trunk. 
First dorsal fin originating above the base of the ventrals 
and but little larger than the second: anal fin small 
originating below the last third of the second dorsal: caudal 
fin short; (€repos, another 3; cxvAdwov, Seylliwm.) 
Small ground sharks hitherto only recorded from Moreton 
Bay. Monotypic.
