A Macri(r}(s like form, with immense, thick, an.siiilar head, with caveriions bones; with 

 quadrate massive snout, and with trunk exceedingly short, running into a short, much 

 compressed, and low tail immediately behind the. vent. First dorsal with about 10 spines, 

 inserted over or in advance of the origin of the pectorals; the second and longest spine 

 slender, obscurely seriated. Ventrals moderate, inserted under or in advance of insertion 

 of pectorals. Head with dense, flaccid skin, thickly covered with small villous scales; 

 scales of body with a few long, slender, curved sjiiues. No lateral line. A series of larger 

 scales along base of second dorsal, which is weak and low. Bones thin and flexible.

Hijmenoi-rphtihis rrassiceps, Vaillant, np, vit., 214, pi. xx, fig. 1. 



Head and anterior part of body very large; the greatest height two-elevenths, its 

 greatest thickness one-twelfth of total length. Head globular in form, its length one-fifth 

 that of the body. Snout targi<l, obtuse. Mouth moderate, inferior. Body greatly con- 

 tracted behind the vent, which is in vertical from iiosterior end of first dorsal. 



Diameter of eye about (me-fourth the length of the head. Width of the interorbital 

 space two-fifths the length of the head. Barbel small and slender. 



Opercula covered by thick skin, only visible upon dissection. Small rough scales cov- 

 ering entire head; those upon body also small, very rough; a row of much stronger ones 

 along the base of the second dorsal. Lateral line not perceptible. About 200 scales in 

 longitudinal row, 51 in vertical row. 



First dorsal small, its second spine slender, covered with weak serrations. Second 

 dorsal low and with feeble spines, its origin separated from the end of the first dorsal by a 

 space equal to twice the length of the base of the latter. Anal much higher than the second 

 dorsal, its anterior rays much the longest; its origin nearly under that of the second dorsal. 

 Pectorals moderate, talciform, reaching beyond origin of anal. Ventrals small, in advance 

 of the pectorals.

Tiie French expedition obtained 17 examples in the Gulf of Ciascony at 1,(;00 meters, 

 on the coast of Boudau at 1,130 to 1,435 meters, and off the Azores at 2.005 meters. It 

 has not yet been found in the Western Atlantic.
