membranes united ; gill-opening extending upwards to lateral line. 
Dorsal fin originating in advance of eye. Left pelvic fin median, with 
long base; right lateral, base shorter. Scales large, rather weakly 
ctenoid on left side, cycloid on right. Lateral line with a strong curve 
anteriorly. 
Several species from the Indo-Pacific; one from Natal. 
ENGYPROSOPON NATALENSIS, Sp. Nov. 
Depth of body 2 in the length, length of head 37. Diameter of eye 
34 in length of head and 3 times interorbital width. Maxillary 
extending to below anterior | of eye; lower jaw } length of head. 
Teeth uniserial. 6 gill-rakers on lower part of anterior arch. Dorsa] 
85. Anal 64. Left pectoral * right = length of head. 40 scales in a 
longitudinal series. Traces of small dark spots on the fins. 
Described from a female 76 mm. in total length ; a male of 55 mm. 
has a spine on the snout, interorbital width 5 diameter of eye, pectoral 
fins as in the female. 
Natal, off mouth of Amatikulu River; depth 26 to 27 fathoms. 
E. latifrons, Regan, (Trans. Linn. Sec. XII, 1908, p. 233 pl. xxv, 
fig. 3) from the Indian Ocean, is very near H. natalensis, but has the 
interorbital region broader (3 diameter of eye in a female of 75 mm.). 
There are other closely related species, including the Japanese #£. 
grandisquama, Schleg., under which name this species has been 
recorded from Natal. 
4. CROSSORHOMBUS, gen. nov. 
(type PLAropHRys pimoRPHUS, Gilchr.). 
Eyes on the left side ; interorbital region concave. Mouth small ; 
teeth small, pointed, uniserial in the jaws; palate toothless. Gill- 
membranes united ; upper angle of gill-opening a short distance above 
pectoral fin ; scaling of head and body continuous below lateral line. 
Dorsal fin originating in advance of eye. Left pelvic fin median, with 
long base ; right lateral, base shorter. Scales large, strongly ciliated 
on left side, weakly ciliated or cycloid on right. Lateral line developed 
on both sides, with a strong curve anteriorly. 
One species from Natal. 
Scaeops kobensis, Jord. and Starks, from Japan, and Engyprosopon 
xenandrus, Gilbert, from Hawaii, belong to this genus.
