pretty even in size ; the first one forms a smooth margin to the narrow, but 

 well-defined notch-band, which is crossed by the lines of growth deeply waved, 

 and extends to the suture, which is not appressed ; outer lip thin, much pro- 

 duced forward, as in Daphnella, but the notch is distinct and very deep, with 

 its edges simple and not reflected ; pillar slightly twisted, without a callus ; 

 canal distinct, slightly recurved ; whorls full and rounded. Lon. of shell, 

 5.75 ; of last whorl, 3.5 ; of aperture, 2.5. Max. lat of shell, 2.5 ; of aperture, 

 1.0 mm. Defl. about 37°.

This little shell has quite the Daphnella shape, but the nucleus, the notch, 

 and its band seem to decide that it should go with the Drillias, until more 

 is known. 



P. (Daphnella?) leucophlegma n. s. 



Shell thin, delicate, pearly white, acute, with nine rapidly enlarging whorls, 

 roundly inflated (especially the last), which gives a turreted appearance to the 

 spire ; nucleus minute, glassy, smooth, simple ; nuclear whorls not separated 

 by any sudden change of character from the rest of the shell ; general sculp- 

 ture consisting of numerous close-set (three or four to a millimeter) narrow 

 plications extending from near the suture obliquely and flexuously across the 

 whorls, in general correspondence with the lines of growth ; on the last whorl 

 fading away anteriorly and barely visible at the periphery ; lines of growth 

 generally pretty distinct ; the whole shell covered with fine, somewhat wavy, 

 spiral grooves and intervening threads, not strong enough to give a rough ap- 

 pearance to the surface, and evenly distributed (twelve to sixteen in a milli- 

 meter) ; aperture large, semilunate ; outer lip thin, simple, much arched and 

 produced at the middle, and rounding broadly to the anterior end of the 

 pillar ; columella w r ith a slight callus, obliquely trimmed to a point, and 

 slightly recurved anteriorly ; notch obsolete, forming no distinct band, though 

 indicated by the lines of growth and by a slight flattening of the whorl just in 

 front of the distinct and well-marked suture, as in Daphnella. Lon. of shell, 

 10.25 ; of last whorl, 6.25 ; of aperture, 4.75. Max. lat. of shell, 4.25 ; of 

 aperture, 2.0 mm. Defl. about 36°.

This pretty little shell may turn out to be a Drillia. It has characters re- 

 calling Daphnella, Beta, and (the immature) Drillia. Until the soft parts are 

 known it can hardly be definitely located.

This specimen resembles Ban's figure exactly, except that it has one whorl 

 more, and is correspondingly larger. I observe, however, that the specimens
