the orbit, midway between the occipital and postorbital ridges, the 

 remaining scales between these ridges being small; scales on opercles 

 similar to those on body, but those on suborbital region are small; 

 tip of snout w ith a spinigerous plate above and below ; underside of 

 head wholly scaleless, even below the angle of preopercle. 



First dorsal spine small but sharp, entirely smooth (with two small 

 spinules in a paratype), longer than the snout, and slightly longer 

 than the soft rays ; base of first dorsal 1.5 in orbit, 1.75 in interdorsal 

 space. Pectoral 2.9 in head. Outer ventral ray reaching past anus, 

 but not to origin of anal, the other rays not reaching anus. 



Color in alcohol brownish, underlaid with silvery on breast and 

 anterior part of sides and with blackish on belly ; underside of head 

 grayish anteriorly, silvery posteriorly, with small grayish brown 

 punctulations; buccal and branchial cavities lined with blackish, ex- 

 cepting a narrow border on inner edge of opercular membrane; peri- 

 toneum blackish, underlaid with silvery. 



Six paratypes, five from Albatross station 5059, at which the type 

 was dredged, and one from station 506G, also in Suruga Gulf ; dej^th, 

 211 to 293 fathoms. Some of these have a shorter, broader snout 

 than the type. In addition, three small specimens, 86 to 90 mm. 

 long, 27 to 30 mm. to anus, were dredged at stations 5059, 5066, and 

 5072, 148 to 297 fathoms ; Suruga Gulf. These differ from the larger 

 specimens in several characters probably due to the difference in size : 

 Orbit, 3.4 to 3.6 in head, 1.4 to 1.5 in snout; snout, 2.3 to 2.4 in head; 

 maxillary, 4.4 to 4.6 ; distance from ventrals to anus, about equal to 

 orbit; distance from anus to anal, 3.3 in orbit; scaly ridges of head 

 strong ; scales of body bearing one to three ridges.
