414 Mr. C. T. Regan on new Fishes from 
HETERONARCE, gen. nov. 
Differs from Narcine in the minute nostrils, the length of 
the anterior nasal valves, which are confluent to form a 
curtain that is not much broader than long and is studded 
with pores, and the lateral position of the posterior nasal 
valves. 
In addition to the species described below, this genus 
includes Narcine mollis, Lloyd (Mem. Ind. Mus. ii. p. 144, 
pl. xlvi. figs. 1, 1a), from the Gulf of Aden, at 130 fathoms. 
Heteronarce garmani, sp. n. 
Very similar to H. mollis, but eyes and spiracles much 
smaller, snout longer, mouth and nasal valves smaller, and 
coloration of lower surface different. Spiracles as large 
as eyes, which ean be completely covered by the lower lids ; 
diameter of eye+spiracle 2 interspiracular width, which is 
about 3 length of snout (preocular). Internasal width 4 
length of snout (preeoral) or 74; width of disc; nasal curtain 
2 as long as broad, with straight posterior edge. Brown 
above ; white below. 
A single specimen, 170 mm. in total length. 
Named in honour of Dr. 8. Garman, in recognition of his 
work on the Selachians. 
Ateleopus natalensis, sp. 0. 
Length of head about equal to its distance from origin of 
anal; length from end of snout to origin of dorsal about }, to 
origin of anal about 4 of total length. Snout prominent; 
eye nearly in middle of length of head, its diameter 7 to 8 in 
length of head; interorbital width 4 in length of head. 
Mouth wide; lips smooth or with minute papille; lower jaw 
toothless, included within upper, its length 4 length of head ; 
angle obtuse, without spine. 10 gill-rakers on lower part 
of anterior arch. Dorsal 9-10; height equal to length of 
pectoral. Anal+caudal 104-108. Pectoral 3 to # length 
of head, pelvics 2 to 3 length of head, slightly expanded 
distally. Greyish ; fins blackish. 
Two specimens, 480 and 540 mm. long. 
In the larger the length of the pectoral fin is 3 and that of 
the pelvic fin $ the length of head; in the smaller the pectoral 
is # and the pelvic 3 the length of head. 
A. indicus, Alcock, from the Indian Ocean, is well distin- 
guished by the fewer anal rays (A+C 76-80).
