deeper (depth 12 in length), the anterior profile steeper, and 
the dorsal fin higher, bearing a considerable general resem- 
blance to the young H. typus figured by Kner and Stein- 
dachner. Gilchrist’s specimen was only 72 mm, (to base of 
caudal), and had the body still deeper and other juvenile 
characters. 
The following appear to be new to science :— 
Scyliorhinus (Halelurus) polystigma, sp. n. 
Snout rounded, its preeoral length 4 the distance between 
outer edges of nasal flaps; latter without cirri, not confluent 
with upper lip, separated by an interspace equal to twice the 
length of the posterior edge of either. Mouth 14 as wide 
as long ; no labial folds; upper lip not overlapping lower at 
angles of mouth. Posterior gill-openings smaller and closer 
together than anterior. First dorsal origiy ating above end of 
base of pelvics ; anterior angle rounded, , vsterior rectangular ; 
base ? distance from second dorsal, which is larger than first 
and originates above end of base of anal. Length of base of 
anal 1? that of first dorsal, 14 that of second, 2 its distance 
from caudal. Pectoral rounded, extending nearly 2 the 
distance from its origin to that of pelvics, which in the male 
are united for about the basal third of their posterior edges. 
Upper surface covered with numerous small rounded spots. 
A single specimen, 320 mm. in total length. 
Apparently related to S. buergeri, Mill. & Henle, from 
Japan, but resembling the subgenus Scyliorhinus in the 
united pelvic fins. 
Seyliorhinus (Cephaloscyllium) sufflans, sp. n. 
Snout obtusely pointed, its preoral length 4 the distance 
between outer edges of nasal flaps; latter without cirri, 
separated by an interspace which is 13 the length of the 
posterior edge of either and 5 times their distance from edge 
of lip. Month twice as wide as long ; no labial folds. Gill- 
openings subequal ; last two closer together than others. 
First dorsal originating above middle of pelvics; anterior 
angle rounded, posterior obtuse; base 13 that of second 
dorsal and equal to its distance from that fin, which ends 
nearly above end of anal. Base of anal nearly equal to that 
of first dorsal, longer than its distance from caudal. Pectoral 
with rounded angles, extending not quite 4 the distance from 
its origin to that of pelvics. Greyish, without distinct spots 
or markings, 3 
A single specimen, 750 mm. in total length.
