The collection contains 20 specimens uf tin- species, representing the following localities: Dredging 

 stations 3486, 3489, 3490, 3449, 3459, 4223. 4227. 4228 (4 specimens), 1249, (tag no. 2898 , 4253 (tag no. 

 2905), 4283, 4284 (3 specimens), 4285, 4289 (5 small specimens and one large example qo. Mono.. 4290 

 (tag no. 2005). and 1292. These specimens range in length from 4.4 to 15 inches. We have also exam- 

 ined 8 small specimens 3 to 5 inches long dredged among the Santa Barbara Islands at station 2840, and 

 2 specimens (paper tag no. 110 and 111), each about 4.5 in. he- long, from Albatross station 3599, 

 June 9, 1894, in Bering Sea. These specimens had a number of parasites upon them. 



All these specimens agree in the main with the excellent original description of the specie-. Speci-

Body ovate, compressed, both dorsal and ventral outlines gently curved; head moderate; mouth 



medium, slightly oblique, the tip of premaxillarj on a level with pupil, the gaj xtending to under 



nostril; maxillary extending to a little beyond vertical at middle of orbit; mandible to posterior margin 

 of pupil; teeth minute, in narrow hands on palatines, a triangular patch on vomer, hands on upper jaw 



terminating anteriorly in rounded lobes, leaving a vacant space at symphysis, the teeth each side of 

 vacant space slightly enlarged, hand on lower jaw narrow, the symphyseal patch somewhat raised and 

 its teeth. somewhat enlarged, this patch fitting into the vacant space above; lower jaw slightly project ing,

 pale; interorbital space tolerably broad, L.5 in eye, and very slightly concave; cranial ridges rather
