OX THE ANATOMY AND RELATIONS OF THE EURBYPHARYNGID. 
By THEODORE GILL and JOHN A. RYDER. 
The remarkable fish called Hurypharynx was one of the fruits of the ex- 
plorations of the French vessel Travailleur in 1882. A single specimen 
about a foot and a half long was obtained off the coast of Morocco at 
a depth of 2,500 meters (about 1,100 fathoms), and has been partially 
described by M. L. Vaillant under the name Lurypharyne pelecanoides. 
Three specimens of the same general type of fishes were found by the 
United States Fish Commission steamer Albatross in August and Sep- 
tember, 1883, and might be considered to be generically and even 
specifically identical with Lurypharynx pelecanoides were it not for sev- 
eral positive statements made by the describer of that species. 
The problem of the relations of Hurypharnyx to other fishes has 
been discussed by M. Vaillant with what appears to us to be negative 
results and one set of conclusions necessarily contravenes another. But 
it is only just to M. Vaillant to let the opinions as to the affinity of the 
fish enunciated by him be presented in his own language: 
‘“ We may say that the fish presents relations with the Anacanthini, 
with certain Physostomi,such as the Scopelidz and Stomiatide, and also 
with the Apodes. While it resembles these last in the want of ventral 
fins and the imperfection of the opercular apparatus, it differs from them 
too much inits well-developed and absolutely free intermaxillaries to 
allow it to be placed in the same group. As regards the Scopelide and 
Stomiatidse, all the known genera in those families have a very widely 
open branchial orifice: in the former the intermaxillary alone forms —
