438 MAZATLAN tTNIVALTES 



54G. ACLIS TtTMENS, n. s. 



A. t. suhdiaphana, nitidd, alba, inflata ; vertice nucleoso 

 mimito, anfi\ i. et dimidio, decliviter sito ; anfr. normalibus vi. 

 valde tumentihics ; aperhira rotundata, 2'>eritremati coniinuo, 

 acuto ; labio rimulam timbilicalem monstrante. 



This species is more tumid even than A. ascaris, from which 

 it differs in being smooth, with a minute apex. A specimen 

 from Java sand appears exactly like in all particulars ; though, 

 ■with so few characters to judge by in the shell, the animal may 

 be distinct. Lonci. '053, long. spir. "OSo, led. 'OSi, div. 27°. 



Hab. — Mazatlan ; 1 sp. off Chama ; L'pool Col. — ? Java, 

 F. Archer. 



Tablet 2017 contains the specimen (slightly broken.) 



Genus EULIMA, Bisso.

Conch. 111. sp. 7, f. lO.—Proc. Zool. Soc. 1834, p. 7.— Lam. An. 

 s. Vert., vol. viii., p. 451, no. 2.—S. Sf A. Ad. Gen. i. 236. 



Fragments were found of six specimens which may belong to

Sab. — St. Elena, Cuming. — ? Mazatlan ; extremely rare, off 

 Spondj'lus and Chama ; L'pool Col. 



Tablet 2018 contains 2 (broken) specimens. 



548. EuLiMA , sp. ind. (a.) 



Tablet 2019 contains an apical fragment of a species, much 

 smaller than Eu. hastata, with the apex not so stout or rounded. 



JIab. — Mazatlan ; extremely rare, on Spond^dus ; L'pool Col. 



549. EuLiMA , sp. ind. (b.) 



Tablet 2020 contains fragments of a species, somewhat 

 resembling Eu. acuta, Soio. (Proc. Zool. Soc. 1834, p. 8 ; Leios- 

 traca a., H. 4" A. Ad. .- non. Eu. acuta, A. Ad.) but appears 

 a genuine Eidima. It is remarkable for the extremely slight 

 divergence of the spire, though the whirls are not elongated. 



Hab. — Mazatlan ; extremely rare, on Chama and Spondylus ; 

 L'pool Col.
