Spurious Species of Veronicella. The following species are catalogued by Grateloup among the American Vaginuli (Dist. Geog. des Limaciens, 22). They were all described by Rafinesque, and by him placed in his genus Philornyciis (see Binney and Tryon, reprint). From the general inaccuracy of that author, as well as the deficiency of the descrip- tions, I think they should be excluded from this or any

Fig. B. notabilis, partially extended, en- larged. BINNEY A, J. G. Animal beliciform, obtuse before, rapidly acuminated behind; mantle sub- central, extending anteriorly beyond the shell; a distinct locomotive disk; no caudal mucus pore; respiratory oriBce poste- rior, on the right edge of the mantle; anal orifice contiguous to last: genital orifice behind the right eye-peduncle. Shell entirely external, ear-shaped, nearly fiat, about one third as long as the animal, which it does not half cover when retracted. Spire flattened, forming two horizontal volu- tions, last whorl enormously expanded and slightly arched. Columella distinct, entire, hiding the interior of the convo- lutions; peristome simple, acute. In estivation the part of the animal ex- cluded from the shell is protected by a thick, white, parchment-like epiphragm. A senus of the Mexican fauna, whence it has been introduced on Guadelupe Island off the west coast of Mexico, and Santa Barbara Island, coast of California. The jaw is thick, slightly arcuate, ends blunt; anterior surface with six well-developed ribs, denticulating either mar- gin, situated on the central third of the jaw, and as many subobsolete ribs on each outer third; no median projection.
