12 Records of the Indiaw Museum. [Vor. VII, 
A large number of examples, the majority, unfortunately, in 
a badly damaged condition, were obtained at Station 391. 
Brauer (1908, p. 217) has provisionally placed S. engraulis as 
a synonym of S. (Myctophum) coeruleus, Klunzinger. 
Although agreeing very closely with the description of S. 
coeruleus, the specimens in the Indian Museum, which I refer to S. 
engraulis, differ in a few points, especially in— 
(1) The greater number. of rays-in the pectoral fin: in all 
examples there are 12 present, whereas in S. coeruleus 
there are only Io. 
(2) The greater relative length of the dorsal fin: this was 
invariably greater than the length of the anal fin, not vice 
versa as in S. coeruleus. 
In the present state of our knowledge I consider that it is not 
advisable to unite the two species. 
(I would remark in passing that the smaller of the two speci- 
mens referred by Alcock to S. engraulis and obtained at Station 115, 
Q-xli-go—11° 31’ 40” N., 92° 46’ 40” E.—188-220 fathoms, off the 
Andaman Islands, is undoubtedly an example of S. (Myctophumy) 
splendidus, Brauer.) 
APODES: 
Family ANGUILLIDAE. 
Coloconger raniceps, Alcock. 
1899. Alcock, p. 196.

A single specimen measuring Ig'I cm. in total length was 
obtained at Station 301. 
Uroconger lepturus (/Richardson). 
Congrus lepturus, 1844, Richardson, p. 106, pl. 56, fig. 1—-6. 
Uroconger lepturus, 1870, Gunther, vol. 8, p. 44. 
~ 1908, Brauer , D. 124. 
Uroconger vicinus, 1899, Alcock, D. 200. 
A single example, measuring 55 cm. in total length (including 
caudal), was obtained at Station 388 and was referred to this 
species. Brauer (/.c.) considers that the specimens obtained by 
Alcock and described by him under the name U. vicinus, Vaillant, 
are in reality not members of that species. 
As he points out, in U. vicinus the proportion of head length 
to total length is 1: 11, whereas Alcock gives it I; 7-8 in his speci- 
mens—a fact which I have verified. 
The points on which Alcock relies to separate his examples 
from U. lepturus are: (1) the reduced number and larger size of 
the vomerine teeth; (2) the widely separated gill-openings ; and 
(3) the increased distance from gill-opening to dorsal fin. Brauer
