EASTERN PROVINCE NORTHERN REGION SPECIES. 187 



From Gaspe to the north of Lake Superior, and through New Eng- 

 land ; it may therefore be considered a species of the Northern Eegion. 

 Also Tacoma, Wash Ter. 



The animal is described by Morse as bluish-white, with head, neck, 

 and eye-peduncles mottled by streaks and dots of bluish-black ; disk 

 yellowish-white. 



Jaw but slightly arcuate, of uniform width throughout, long, nar- 

 row, ends blunt ; anterior surface with coarse fig. ise. 

 striae, not modifying the concave margin, ^„^<0^^^^I^^^MFrh^

jection. Ja-w of p. asteilscus. (Morse.) 



Liugual membrane (Terr. Moll., V, Plate lY, Fig. C) : Morse gi\es 

 77 rows of 13-1-13 teeth ; 6 perfect laterals. I counted 11-1-11, with 

 5 perfect laterals. The reflected portion of the central teeth is quite 

 small. The marginal teeth are like those of Fupa. 



Genitalia not examined.

oblique, falling forward. Diameter, -^^ ; axis ^ poll. (Gould.) fig. is?. 



Hyalina imuper, Gould, Pr. Bost. Soc. N. H., vi, 423; Otia, 102. 

 Fatula })auper, \V. G. Binney, Terr. Moll., v, 166. 



An Asiatic species, found also in Alaska, if 1 am right in 

 referring to it the Ounalaska specimens called ruderata by 

 Dr. Cooper (Am. Journ. Conch., Y, 202). 



The specimen figured was collected by Mr. Dall at Petro- 

 paulauski, Kanitschatka. He also found the species over all •^''«^«''- 

 of Alaska north and east of Sitkan Islands. It is referred by Kein- 

 hardt to Crotikhitei, but erroneously, I believ^e. 



The young shell, characterized by a mottled color when fresh, was 

 described by Morelet as H.JIoccata, a year before Gould described^a?<2;(?r. 

 Morelet referred the adult shell to niderata.
