 3| to 4| in head; snout a little longer than eye; lower jaw scarcely 

 included; 1 or 2 strong, conical teeth on each side behind the narrow 

 premaxillary band of teeth; teeth on vomer, none on palatines; no

Sea of Okhotsk, north to the Kuril Islands. Our specimens, :> in 

 number, the longest 25 cm. long, from Shana Bay, Iturup Island. 

 The scales are entire, strongly marked with concentric stria\ The 

 dorsal spines number 62, 63, 63, 64, 64. Dor.sal ocelli are present on 

 all our specimens, 2 of them )>eing faintly visible, even in the youngest, 

 55 mm. long. (Named for Professor Dybowskii. its first collector.) 



33. PHOLIDAPUS GREBNITZKII Bean and Bean. 



Pholidapus grebnitzkii Be ax and Bean, Proc. U. S. Nat. Mus., 1896, p. 390, 

 pi. xxxiv; Volcano Bay, Japan. (Coll. Col. Nicolas A. Grebnitzki.) 



This species from Volcano Bay, near Mororan, may differ in the 

 smaller number of dorsal spines and in the absence of dorsal ocelli. 

 Not having examined the types, we are not sure of its distinction from 

 Ph. di/howsk/i. 



The specimens are 141 mm. long, including caudal; 126 mm. to base 

 of caudal. The head (22 mm.) is equal to the greatest depth of l)ody. 

 The eye is slightly longer than the snout and one-fourth as long as 

 the head. The interorbital space is narrow, two-thirds of the length 

 of the eye. The naked head resembles that of Pholh; its length is 

 contained about 5^^ times in total length without the caudal. The 

 mouth is small and very oblique; the mandible is slightly included 

 and has a well-developed lip. The maxilla is partly concealed under 

 the preorbital bone; it does not quite reach to below the anterior 

 margin of the pupil. The anterior nostril is midwav between the 

 eye and the tip of the intermaxilla. Seven nmcous pores around the
