LimnsEa bulimoides, Lea, Proc. Am. Phil. Soc. II, 33 (1841); Trans. IX, 

 9 (1844) ; Obs. IV, 9.— Haldeman, Mon. 44, pi. xiii, f. 9, 10 (1842). 

 — DeKay, N. Y. Moll. 75 (1843). 



To Mr. Lea's original description I have added Fig. 96, copied 

 from an authentic specimen. Among tlie specimens in the col- 

 lection Nos. 8525 and 88'70 were determined by Mr. Lea. 



Found by Dr. Hayden, in his explorations of the Yellowstone, 

 and at several points in the Pacific States. 



I have seen specimens strongly resembling Bulimulus pilula. 



Fig. 97. 



L.iinnaca, SOlida, Lea. — Shell acutely conical, solid, smooth, horn 

 color ; spire rather turreted ; whirls five ; columella reflected ; aperture 

 subovate. 



Hab. Wahlamat, near its junction with the Columbia River: 

 Prof. Nuttall. My cabinet, and cabinet of Prof. Nuttall. Diam. 

 5-20th, length 8-20th of an inch. 



A single specimen of this species was among the shells given 

 to me by Prof. Nuttall. It differs from any species which I 

 know, in being more solid. In this specimen the interior is 

 brownish. (^Lea.) 



Limnxa soUda, Lea, Trans. Am. Phil. Soc. VI, 94, pi. xxiii, f. 91 (18.S9) ; 



Obs. II, 94.— Haldeman, Mon. 3(3, pi xi, f. 10-13 (1842).— DeKay, 



N. Y. Moll. 75 (1843). 

 Limnxa apicina, Lea, Trans. Am. Phil. Soc. VI, 102, pi. xxiii, f. 94 (1839) ; 



Obs. II, 102.— KtisTER in Ch. ed. 2 (Limnxus), 48, pi, viii, f. 31-33. 



Pr. Gould quotes L. apicina from Oregon. 



"Haldeman places L. apicina in the synonymy of L. solida, as 

 does also DeKay and Kiister. Copies of the descriptions and 

 figures of both species are given. 



Limnxa apicina. Lea. — Shell obtusely conical, rather solid, smooth, 

 horn colored ; spire rather short ; whirls four ; columella re- 

 flected, aperture subovate. 



Ilab. Wahlamat, near its junction with the Columbia River : 

 Prof. Nuttall. My cabinet, and cabinet of Prof. Nuttall. Diam. 

 .3, length .4 of an inch. 



This small species is rather more globose than usual. It is' 

 Limncea <listi"giii«li«'i by a dark apex. Within the outer lip there is a 

 apicina. dark-browu band. (Lea.)
