FISHES OF HAWAIIAN ISLANDS. 
657 
Head 26.5 hundredths of length to base of caudal; depth 21; depth of caudal peduncle 3; length 
of filamentous dorsal ray 23; filamentous ventral ray 24; outer ventral ray 12; pectoral 20; distance 
between ventrals and anal 40; length of anal base 20. Longitudinal diameter of orbit 25 hundredths of 
length of head; interorbital width 26; length of snout 30; distance from tip of snout to front of pre- 
maxillaries 11; length of maxillary 47, its tip noticeably behind posterior margin of orbit; length of 
mandibular barbel 9. D. rays 4+51; A. 38; P. 18 or 19; V. 6. About 130 transverse rows of scales on 
sides, the number uncertain owing to the irregularity of the series. 
Teeth in narrow bands on jaws, and in a small cluster on head of vomer; gill-rakers very short, 
3+11. 
Body entirely denuded of scales and with light gray appearance, the membranes of scale-pouches 
blackish; gill-membranes and pectorals, ventrals, and caudal deep blue; lining of the gill-eavity and 
abdominal wall black. 
In 8 specimens of A. microlepis from Alaska, the dorsal formula is as follows: 4-50, 4—53, 4-54, 
4- 54, 4-54, 4-54, 4-54, 4-55. In 6 specimens the anal rays are 40, 40, 41, 42, 43, 44. 
Antimora rhina Garman, from the Panama region, is said to differ from microlepis in the longer 
dorsal fin (4 or 5-54 to 56) and the smaller scales (145). As is seen from the dorsal formula of micro- 
lepis given above, the latter does not differ from rhina in the size of the dorsal fin. It seems probable 
that the 2 species are identical, especially as a careful comparison of Garman’ s description with typical 
microlepis fails to develop any differences. 
Lsemonema rh.odoeh.ir, new species. Fig. 255. 
Type, 116 mm. long, from station 3810, off the south coast of Oahu, depth 53 to 211 fathoms; type, 
No. 51623, U. S. Nat. Mus. 
Length of head 25 hundredths of total length without caudal; length of snout 7.5; interorbital 
width 3.5; longest diameter of orbit 7; length of maxillary 12; length of barbel 6; depth of body 19; 
least depth of caudal peduncle 2.5; length of ventrals 27 ; length of pectorals 18; first dorsal ray 12. D. 
5- 64; A. 59; P. 24; V. 2. Scales in about 130 cross-series above lateral line, 10 or 12 scales between 
lateral line and base of anterior dorsal rays. 
Snout depressed, evenly rounded; distance between nostrils about equal to distance from posterior 
Fig. 255 . — Lxmonema rhodochir Gilbert, new species. Type. 
nostril to eye; anterior nostril in a delicate tube, the posterior portion of which is the highest; inter- 
orbital region narrow, flat or very gently concave; eye comparatively small, slightly shorter than 
snout; snout not protruding beyond premaxillaries; mandible included; maxillary reaching a vertical 
from middle of eye, its length half that of head; teeth finely villiform, in a wide band on premaxil- 
laries, a narrower band on mandible, and apparently a single series on head of vomer; palatines tooth- 
less; branchiostegals 7; gill-membranes united anteriorly by a delicate membrane which is free from 
isthmus; gill-rakers on outer arch 5 + 11, the longest + head; a moderate slit behind fourth gill; 
pseudobranchiae reduced, covered by membrane. 
Distance from tip of snout to origin of dorsal 3.7 in total length without caudal, the front of dorsal 
vertically above base of lower pectoral rays; base. of first dorsal equal in length to half the ocular
