140 “TERRA NOVA” EXPEDITION. 
Lampadena chavesi, Collett (Pl. VI, fig. 8). 
Four specimens, 10 to 12 mm. long, may belong to this species. I count 12-13 
dorsal, 13-14 anal, and 15 pectoral rays and 38 myotomes. The fins are placed as in 
the adult fish. The maxillary extends to below the middle of the eye. On each side 
there is a photophore in front of the eye, another at the base of the pectoral fin, and a 
third above the base of the pelvic fin. Two examples have 2 mid-dorsal stellate 
blackish spots behind the adipose fin and a mid-ventral series of 3 or 4 linear spots 
behind the anal fin. 
Station 17. South of the Canaries. 26° 17’ N., 20° 54’ W. 10 metres. June 30th, 
1910. 
Lampanyctus maderensis, Lowe (Pl. VI, fig. 6). 
An example of 9 mm. shows the supraorbital ridge ending in an antrorse spine ; 
the cleft of the mouth extends to below the posterior edge of the eye. The myotomes 
number 36 and the fins are as in the adult fishes figured by Goode and Bean, and 
Brauer. There is a bar of pigment at the base of the caudal fin. In specimens of 
5 mm. the spine is not developed, the mouth is smaller, and the adipose fin is longer. 
Station 50. Tropical Atlantic. 18°8., 31°45’ N. Surface. May 7th, 1913. 
Lampanyctus macropterus, Brauer (Pl. V1, fig. 5). 
A specimen of 10 mm. may belong to this species; it is very similar to the 
example of ZL. crocodilus of the same size figured by Holt and Byrne (Fisheries Iveland 
Sci. Invest., 1910, VI, pl. I, fig. 3). There are 12 dorsal and 20 anal rays and 40 
myotomes. There is a black spot at the base of the caudal fin, another above the anal 
papilla, and some smaller ones on the lower part of the head. 
Station 135. Spirits Bay, near North Cape, New Zealand. 3 metres. September 
Ist, 1911. 
Lampanyctus longipinnis, sp. n. (Pl. VI, fig. 9). 
Dorsal 22. Anal 25. Myotomes 38. Evidently related to L. procerus, Brauer, 
differing in the more numerous dorsal and anal rays. 
A young fish of 15 mm. 
Station 113 (N.E. of Three Kings Islands). 33° 12’ S., 171° 05’ HE. 3 metres. 
August 9th, 1911. 
APODES. 
Following the plan adopted by workers on this group, I use the name Leptocephalus 
as a generic term for larval Hels, and give new specific names to those that cannot be 
identified. 
Leptocephalus acuticeps, sp. n. (Pl. VII, fig. 5). 
Very similar to L. oxycephalus, Pappenh. (Deutsche Siidpolar Exped. XV, Zool. VI,
