A single specimen 15°5 cms. in length (including the caudal 
fin) was obtained at Station 391. 
A careful comparison with Alcock’s type specimens failed to 
reveal any discrepancies. 
So far as I am aware, the only previous records of the occur- 
rence of this species are at “‘ Investigator” Station 1—21° 6’ 30” N., 
89° 30’ 00” E.—in 405-285 fathoms, and ‘‘ Investigator’’ Station 
21I—23° 00’ 00” N., 66° 08’ 00” E.—in 609-620 fms. 
HOLOCEPHALI. 
Rhinochimaera sp. 
A single egg-capsule, in a fresh state and containing an em- 
bryo, was obtained at Station 391. 
The capsule was black in colour and, as regards general ap- 
pearance, closely agrees with the description of the capsules of 
R. atlantica obtained off the W. coast of Ireland (Holt and Byrne, 
IQLO, p. 22, pl. iv, figs. 4-5): 
There is in the Indian Museum an egg-capsule labelled 
Rhinochimaera indica that was obtained by Alcock in 1890 
(Ann. Mag. Nat. Hist. (vi), vol. viii, p. 21) at St. 112—13° 47’ 
30” N., 92° 36’ 00” E.—in 561 fathoms, and was attributed by him 
to a species of Callorhynchus, subsequently receiving the name of 
C. indicus from Garman in 1899 (Mem. Mus. Comp. Zool. Harvard, 
VOl, xxiv, ‘Pp. 21): 
Bashford Dean, who had an opportunity of examining this 
specimen, has expressed the opinion that it is, in reality, a capsule 
belonging to a species of Harriotta (Chimaeroid fishes and their 
Development, B. Dean, 1906), a view with which I am in complete 
agreement. 
A comparison of the present specimen and Alcock’s example 
showed at once that they could not belong to the same species. 
In the following table I have given the measurements of both 
these capsules and, for purposes of comparison, the measurements 
of one of Holt and Byrne’s examples of Rhinochimaera atlantica.
