The dorsal third of the body is liberally sprinkled with brown 

 punctulations. The base of the anal bears 4 or 5 larger pigment 

 spots. There are a few pigment spots on the caudal peduncle. A 

 ring of small pigment spots nearly encircles the eyes, and the snout 

 and anterior dorsal surface of the head likewise bear chromatophores. 

 At the symphysis of the dentaries there are a few spots which extend 

 nearly half the distance down each dentary. The rest of the body is 

 without dark pigment except along the ventral midline between the 

 pectoral and pelvic fins where the body musculature is not complete 

 and the blue-black peritoneum is exposed. 



Remarks. — This species is most closely related to Lestidium (Bathy- 

 sudis) speciosum. It differs from that species by the presence of teeth 

 on the vomer, the characteristic dentition of the tongue and pharynx, 

 and the fact that the upper jaw extends to or beyond a vertical from 

 the posterior edge of the eye. 



The subgenus Bathysudis, which Parr (1928) has introduced for 

 L. speciosum and to which the present species clearly belongs, should 

 probably be recognized as a separate genus. The comparatively 

 short and rounded body, the short conical snout, and the wide gape 

 extending to or beyond the anterior edge of the eye mark these two 

 species from the rest of the genus Lestidium, for the tendency in that 

 genus is toward a long snout with the maxUlary not reaching to the 

 eye and toward a long slender body with a comparatively short tail. 



All the specimens were taken in moderately shallow water, the 

 deepest net having only 170 meters of wire out. Both stations were 

 taken in the northern part of the Gulf of Alaska, station 11 8B near 

 the mouth of Prince Williams Sound, and station 120 near Cape St. 

 Elias. 



Named for Dr. A. E. Parr, in honor of his extensive work with 

 deep-sea fishes.
