400 TERRKSTRIAL AIR-BREATHING MOLLUSKS. 



Bulimics decollatus and B. mutilatua, Say, = Stenogyra decollala. 



Bulimus subulus, W. G. Bin-n., = Stenogyra octonoides, 



Bulimus gracillimiis, W. G. BiNK., = Stenugyra gracillima. 



Bulimus harpa, BiNN., = Acautkinula harpa. 



Bulimics carinatus, Bkuq., Eneyel. Meth., I. 301 (1792); Bosc, IV. 89 (Buc- 

 cinum, Lister & Petiver), is an exotic Melanian, not inhabiting Virginia. 



Bulimics urceus, Brug., Encycl. Meth., I. 298 (1792), from Missis>i[)pi Kiver, = 

 Ampullar ia. 



Melania striata. Perry, Conch., PI. XXIX. Fig. 5, "New California," ia .Bw/i- 

 mus melania, F^russac. 



Bulimus BerlandierianuSy BiNN., in Am. Journ. Conch., 1865. Amer. bor., Pfr., 

 Mon., VI. 153 (1868), probably confounding the Limmean Bulinus. 



Bulimulus Calif arjiicus, Reeve. Shell somewhat acurainately ovate, rather thin, 

 scarcely umbilicated ; whorls 6 in number, smooth ; columella reflected, lip 

 simple ; cream-color, encircled with interrupted transverse blue-black zones 

 {Reeve, Con. Icon., 378). Is not a California species, but probably Mexican. 

 See L. & Fr.-W. Sh., I. 199. 



Columna Californica, Pfeiffer. Shell subulate, thin, with very crowded, ob- 

 lique striae or wrinkles, waxen white ; whorls 12 to 13, the upper convex, the 

 last three or four flat, the last exceeding slightly one sixth the shell's length, 

 sharply carinated at base, below the carina somewhat hollowed out ; columella 

 arched, thickened, subtruncated, reaching the base ; aperture somewhat four- 

 sided ; peristome simple, acute. Length 23, diameter 3^ mill. ; aperture, 4 

 mill, long, 1\ wide. 



Achatina Californica, Pfeiffer, Symb. ad. Hist. Hel., 111. 89 ; Mon. Hel. 

 Viv., II. 267. — Reeve, Con. Icon., 115. —W. G. Binney, Terr. Moll., 

 IV. 26, PI. LXXIX. Fig. 19 ; L. & Fr. W. Sh., I. 190. —Bland, Ann. N. 

 Y. Lye, VIII. 166, Fig. 10 (1865). 



Columna Californica, Chenit, Man. de Conch., I. 431, Fig. 3172. 

 Referred to Monterey, California, but certainly not found there. I have given a 



copy of Reeve's figure, and a figure of a specimen from Bogota, New Grenada, 



which seems identical with it in L. & Fr.-W. Shells, I. The species is a 



Bhodea.
