DAPHNELLA. 313 



Section TERES, Bucq., Dautz. et Dollf. 

 D. ANCEPS, Eichwald. PI. 18, fig. 39 ; PL 32, fig. 31. 



Shell encircled by spiral ridges, of which there are from 20 to 

 25 on the body-whorl, frequently alternately larger and smaller ; 

 light yellowish brown, usually irregularly spotted with chestnut, 

 forming interrupted longitudinal streaks. Length, 8-15 mill. 



Norway to Mediterranean, Madeira and Canaries. 



Var. CONCOLOR is without the chestnut spots. 



The synonymy includes D. teres, Forbes, a name under which 

 it is perhaps more extensively known. Reeve's figure of teres 

 (PI. 18, f. 39) being very bad, I add another, from Forbes and 

 Hanley (PI. 32, f. 31). Other synonyms are D. La Vise, Calcara ; 

 D. borealis, Loven ; D. fusiformis, Requien ; D. polyzonatum, 

 Brugnone, and D. Barbieri, Brusina. 



D. AM(ENA. Sars. PL 20, fig. 86. 



Shell thin, pellucid, interstices of the revolving ridges longi- 

 tudinally striate, lip-sinus profound ; light brownish. 

 Length, 8 mill. 



Arctic Norway. 

 Section ZAFRA, A. Adams. 



There appears to be much uncertainty as to the limits of this 

 group. Adams himself includes the West Indian minute Clathu- 

 relloe discovered by d'Orbigny and figured by Reeve on PL 39 

 of the Conch. Icon., although they do not appear to me to pos- 

 sess any characters apart from ordinary Clathurellae. As will 

 be seen below, there are differences of opinion as to some of the 

 other species. 



D. MITR^EFORMIS, A. Adams. 



Whorls six-and-a-half, rather flat, longitudinally ribbed, the 

 plicae somewhat distant, oblique ; last whorl constricted in front 

 and obliquely sulcate ; white, with an obscure chestnut band at 

 the sutures, the last whorl with a narrow chestnut band on the 

 periphery, and chestnut-tinted at the base. 



Japan. 

 Not figured. 



Columbella zonata, Gould (Manual, v, 172), also unfigured, is 

 doubtfully referred here by Mr. E. A. Smith. If identical, it has 

 priority of two months in publication.
