172 Dull Diagnoses of New Species of MollusJcs* 

 Actaeon (Rictaxis) pairs ei sp. nov. 



Shell with one smooth, polished nuclear and three or more subsequent 

 strongly sculptured whorls; apex sinistral, immersed; spire very short 

 and blunt; body sto*t, ovate, slightly peripherally flattened; sculpture 

 of strong, subequal, spiral riblets, covering the whole shell, separated by 

 slightly narrower, coarsely punctate channels; outer lip sharp; pillar 

 obliquely subtrurtcate in front, twisted, vertical, with a prominent plait- 

 like edge, and a moderately prominent plait about midway of the ex 

 posed portion; body with a very thin wash of callus; color of the shell 

 yellowish subtranslucent white. Length -of shell, 8.0; of aperture, 7.25;. 

 max. breadth of shell, 5.0 mm. 



This is immediately distinguishable from A. punctocoelata Cpr., by 

 its short spire, stouter form, and absence of the blackish color bands.- 

 The specimen described seems not quite mature. It is No. 10^,301, IL-

Clathuretfa fowef sp. nov. 



I 



Shell translucent white, with a brownish-pink flush on the spire and' 

 base; nucleus smooth, polished,, rounded, aird rather inflated, of onr 

 whorl; subsequent whorls, five (or more), sculptured with (on the penul 

 timate whorl 13) short axial rib-lets, slightly oblique with narrower inter 

 spaces, the riblets confined to the peripheral part of the whorl and sepa 

 rated from the suture behind by the spirally striated anal fascicle; spiral 

 sculpture covering the whorl, of slender ffattish threads with wider in 

 terspaces, one thread at the shoulder more prominent than the rest, form 

 ing a wavy keel over the riblets; suture inconspicuous, closely appressed: 

 aperture narrow, canal short, anal snlcus shallow, close to the sutures- 

 outer lip prominent, thickened, the edge sharp and incurved; canal short, 

 slightly recurved, pillar lip smooth. Length of shell, 7.7; of last whorl r 

 5.0; max. diameter of shell, 3.3 mm. Another specimen is 9 mm. long. 



This species resemble* Glyphostoma but has, in the specimens seen, no 

 sculptured callus on the pillar lip. It is not closely like any of the 

 species hitherto known from the eoast. It is possible that still older 

 specimens might show some granulation on the inner lip. The type ifr 

 No. 109,302, U. S, National Museum.

Mangilia fancherae sp. nov. 



Shell slender, elongate, of a dark reddish-brown when fresh; nucleus 

 .tome what swollen, smooth, of about two whorls; subsequent whorls about 

 six or seven, similarly sculptured: axial sculpture of numerous low 

 slender flexuous riblets with wider interspaces, extending from the suture 

 to the periphery and obsolete on the base of the shell ; these are crossed
