Urosalpinx macra YerriU, sp. nov. 



The shell is nearly regularly fusiform, consisting of seven whorls, 

 separated by an impressed suture. The spire is somewhat elongated, 

 regularly tapered, and forms one-half the length of the shell. The 

 nucleus is mamilliform, consisting of about two regularly coiled, 

 convex, rounded whorls, of which the first is nearly as large as the 

 secoiul. The lower whorls are crossed by about ten broad, strongly 

 marked, nodulous ribs. The spiral sculpture consists of stout, 

 rounded, rather elevated, revolving cinguli, which rise into oblong 

 nodules or tubercles in crossing the ribs ; of these there are about 

 eight on the body-whorl, besides five or six on the sijjhon without 

 nodules, Ou the penultimate whorl there are five or six primary 

 cinguli, of which two or three around the periphery are considerably 

 larger and farther apart than the others; one, below these, is coinci- 

 dent with the suture and makes it undulating. Between the primary 

 cinguli there are three to five much smaller rounded cinguli, sepa- 

 rated by thin, incised grooves; these cinguli are about equally prom- 

 inent on the ribs and interspaces and do not form nodules. The 

 surface is also covered with fine, close, raised lines of growth, except 

 on the nodules, which ai'e smooth at summit. The aperture is ovate, 

 continiied anteriorly in a rather long, narrow canal, and having a 

 slight posterior notch or sinus at the suture. The outer lip is sharp 

 and regularly arched ; the inner lip is strongly excavated, its curva- 

 ture posteriorly being greater than that of the outer lip. Columella 

 rather elongated, straight, with a somewhat sinuous inner margin. 

 The canal is straight, somewhat elongated and constricted. Color 

 yellowish white ; interior grayish white. 



Length, 13'"'"; breadth, 5-5"""; length of aperture, 7-5"""; its 

 greatest breadth, 2-5'""'.

SiphO hispidulUS Verrill, sp. nov. 



Shell small, short, broad-ovate, with a rather short, bluntly tapered 

 si^ire, obtusely rounded at the tip, and with a swollen body-whorl, 

 constituting the greater part of the shell. Whorls four, rapidly 

 enlarging, convex, with a distinctly carinate, angular shoulder above 

 the middle, above which there is a concave subsutural band, sepa- 

 rated from the suture by an angular, interrupted revolving ridge, 

 next the suture. Besides these two nodose, revolving carinas, there
