 Brit. Assoc. Report, 1863, p. 650, no. 250, h. 



? S. t. parva, regulariter conica, apice acuto, elevato, parum 

 antrorsun sito; albida, liris validis, rotundatis, interdum vix 

 nodulosis; irregiilariter hue et illuc dupliciter vel tripliciter 

 dispositis; margine a. costis extus undato ; cicatrice baud con- 

 spicua. Long. -24, lat. -18, alt. -12 poll., div. 80°. 



Habitat. — Monterey, Cooper. 



One very small specimen was sent by Dr. Cooper to the 

 Smithsonian Institution, so different in sculpture from the 

 most strongly marked specimens of Scurria mitra, that I pre- 

 sume it to be distinct. The ribs, which are stout for the size, 

 are sometimes single, sometimes gathered into twos and threes; 

 with wide interspaces, in which intercalary riblets appear. 



Genus LEPETA, Gray. 



=Propilidium, Forbes. 



The generic place of this species and the last are doubtful,, 

 the animal not having been yet examined. 



Lepeta c^coides. Carpenter. 



Proc. Phil Acad., April, 1865, j). 60: 



The first perfect specimen of this shell was dredged by Dr- 

 Kennerley ; a larger, broken shell, received before by Mr. R» 

 D. Darbishire from the Farrallones Islands, having been passed 

 over as Scurria mitra. A number of small, but beautifully 

 perfect specimens have lately been sent to the Smithsonian 

 Institute from Sitcha. They are thin ; white, tinged with 

 greenish at the margin, and often with pink within; and very 

 delicately sculptured. It is known at once from all the 

 Acmsew by its semitransparent texture and white color ; and 

 from the young of Scurria mitra by its broad, flat shape, ob- 

 tuse apex, and excurved posterior profile. The striulse are 

 more or less expressed, more or less distant, and rarely sligh « 

 ly granular ; they are always most developed on the back, 

 and subobsolete in front. The genus (as described by Forbes) 

 is curiously like an Emarginula without a slit. The Sitcha 

 specimens range to long. -57, lat. '48, alt. -2. In color, sculp- 

 ture, &c., it exactly resembles L. ceeca ; but that species, as 

 dredged off" Norway, by M' Andrew, and as represented in the 

 Cumingian collection, is conical, while csecoides is Ancyloid. 

 Messrs. Adams figure Propilidium ancyloide, Forbes and Hani., 

 under the name of Lepeta cseca; but the examples above quoted
