the texture and sculpture of the surface from Bela and Daphnella. 
P. linearis, Blainv. (lviii, 26). 
ZAFRA, A. Adams. Acuminately oval, tumid in the middle ; 
whorls longitudinally plicate, the last constricted at the base ; 
aperture linear; inner lip effuse, its margin free; outer lip acute, 
subsinuate behind, subinflected in the middle. P. Pupoidea, 
H. Ad. (lviii, 28 . 
DAPHNELLA, Hinds. Shell fusiform, thin, fragile, usually 
striated ; aperture elongated oval, canal very short. Small and 
elegant shells of slight thickness, distinguished from Defrancia 
by their elongated body-whorl, tenuity and sculpture. No 
operculum. PP. ornata, Hinds (lviii, 29). 
MITROMORPHA, A. Ad. Shell small, elongately fusiform; whorls 
flattened, with revolving lire, and sometimes longitudinally 
plicate. Aperture narrow; columella straight, slightly trans- 
versely lirate; lip acute, smooth within, scarcely sinuated pos- 
teriorly. It is a Mitriform Daphnella, of small size, with lirate 
whorls. Distr.—California, Japan. JM. gracilis, Carp. (lviii, 30). 
CITHARA, Schum. (Mangelia, Reeve [not Leach’. Otocheilus, 
Conr. Cytharella, Monts.) Fusiform, polished, longitudinally 
ribbed; aperture linear, truncated in front, slightly notched 
behind; outer lip margined, denticulated within; inner lip 
frequently finely striated. The animal has the mantle-margin 
slightly dilated on the right side. No operculum. Over 50 
species occur at the Philippine Islands. P. Stromboides, Reeve 
(Iviii, 31). 
cyTHAROopPsSIS, A. Ad. Differs from Cithara in having a sub- 
produced recurved canal and cancellated surface. C.cancellata, 
A. Ad. Japan. 
GLYPHOSTOMA, Gabb. Like Cithara, having numerous colu- 
mellar plaits in adult specimens, but with a lengthened canal 
and deep narrow posterior lip-sinus. P. dentifera, Gabb (lviii, 
32). A number of recent exotic species have been referred to 
this group. 
MANGELIA, Leach. (Bellaspira, Conr.) Fusiform, mostly longi- 
tudinally ribbed; spire elongated, turriculated, acuminated ; 
canal short, more or less truncated; columella smooth; sinus 
near the suture. Nooperculum. P. ponderosa, Reeve (lviii, 33). 
TYPHLOMANGELIA, M, Sars. Narrow and elongate, spire pro- 
duced conic, whorls many, nodosely angulate in the middle, 
aperture narrow, with distinct sinus, the outer lip simple, arcuate 
and inflexed in the middle. Opereulum pyriform. Animal 
without eyes. P. nivalis, Lov. (lviii, 34). 
SPIROTROPIS, Sars. Shell elongated, turreted, spire produced, 
the obtuse apex mammilliform, whorls numerous, carinated in the 
middle, aperture narrow, oblique, with a short canal, sinus deep,
