appressed; axial sculpture of (on the last whorl about 20) narrow- 

 rounded ribs extending from the suture over the periphery but niore 

 or less obsolete on the base; the interspaces wider; spiral sculpture 

 of numerous close-set rounded threads over the whole surface but not 

 nodulating the ribs; anal sulcus very shallow, outer lip thin, nearly 

 straight, mner lip erased, canal very short, hardly differentiated 

 from the aperture; height of shell, 10; of last whorl, 7; diameter, 

 5.5 mm, U. S. Nat. Mus. Cat. No. 214224.

PHILBERTIA CAPANIOLA, new species. 



Shell smaU, strongly sculptured, yellowish wiiite, elevated, with 

 about six whorls, includmg the smooth minute nucleus of about one 

 whorl; suture distinct, rather deep, whorls well rounded; axial 

 sculpture of (on the last whorl 11, omittmg the fhial varLx) narrow 

 rounded ribs with a slight shoulder, extending to the canal, with 

 wider intei-spaces, both crossed by the spirals but without nodula- 

 tion; spiral sculpture of (on the spire in front of the shoulder about 4) 

 well-defined cords with narrower interspaces, v/hich become more or 

 less obsolete on the last whorl; aperture narrow, the anal sulcus 

 shallow, and producing no very marked fasciole; outer lip infolded, 

 thick, with a varical swelling behind it, simple withm; body erased, 

 piUar short, straight; canal hardly differentiated; height of shell,

 Mus. Cat. No. 150992a. 



Type-locality. — Near San Diego, southeast of Point Loma, in 12 to

MANGILIA (KURTZIELLA) ALESIDOTA, new species. 



Shell small, yellowish, with on the last whorl a faint dark band in 

 front of the suture and an obscure dark line at the periphery, with a 

 dark flush on the canal; with six whorls, including a minute smooth 

 nucleus followed by a minutely reticulated second whorl, and then by 

 the adult sculpture; suture distinct, slightly appressed, the anal 

 fasciole occupying the space between it and an angular shoulder; 

 axial sculpture of (on the penultimate whorl, 15) narrow, sharp, 

 arcuate ribs extending from the suture over the periphery, with 

 wider interspaces; there are also minute incremental lines roughening 

 the spirals; spiral sculpture of numerous minutely channeled grooves 

 with wider flattish intei-spaces (the latter sometimes v.dth a smaller 

 median groove) covering the whole surface; aperture narrow, with a 

 wide very shallow anal sulcus; outer lip thin, sharp, body erased, 

 pillar straight, axis pervious, gyrate; canal hardly differentiated;
