Genus SCAPHANDER Montfort 



SCAPHANDER STIGMATICA, new species 



Shell much resembling Scaphander nohilis Verrill, from which it is 

 best distinguished by a differential diagnosis. The body is flatter at 

 the apex, shorter, and consequently has a more rotund appearance; 

 the aperture especially in front, is narrower and less expanded; the 

 sculpture in nohilis comprises small rounded-rectangular punctures 

 between flattened spiral interspaces and concentric threads; in the 

 present species the punctures are larger, circular, and close together, 

 the intervening reticulum so fine that only toward the ends of the 

 shell, especially in front, are the spirals wide enough to show flatten- 

 ing. The result of these differences is that while nohilis on a casual 

 glance looks almost smooth, the present species has a roughly punc- 

 tate appearance. Longitude, 38; maximum latitude, 26 mm. U. S. 

 Nat. Mus. Cat. No. 9596. 



Station 2127, United States Bureau of Fisheries, in 1,639 fathoms, 

 greenish mud, south of Cuba. This shell was referred to as S. nohilis 

 in my Blake report (pt. 2, p. 53), but under more careful microscopic 

 scrutiny appears to be distinct. The single specimen is dead but 

 well preserved. 



Family DIAPHANIDAE 



Genus DIAPHANA Brown 



DIAPHANA FLORIDANA. new species 



Shell small, inflated, thin, whitish, with an involved spire; surface 

 smooth except for more or less conspicuous incremental lines; apex 

 a small dimple, the posterior commissure of the aperture narrowly 

 rounded, the anterior part expanded, rounded in front, the thin lip 

 passing insensibly into the strongly thickened pillar-lip, with a con- 

 spicuous coating of enamel on the body. Length, 4; diameter, 3.5 

 mm. U. S. Nat. Mus. Cat. No. 107932. 



Off Fernandina, a single specimen. 



The form is slightly pyriform. 



Family PHILINIDAE 



Genus PHILINE Ascanius 



PHILINE LUCIDA, new species 



Shell minute, translucent white, flattish, of about two whorls, the 

 apex depressed, minute, with a deep suture; the posterior commissure 

 of the aperture rising roundly above the spire; surface finely spirally 

 grooved, the grooves microscopically punctate; general outline of the 

 depressed, last whorl ovate, the test very thin, the margin simple, 

 the arch of the posterior commissure about equal to the curve of the 

 spire opposite; the pillar lip slightly thickened and reflected, a thin
