273 DR. P. P. CARPENTER ON NEW SPECIES 



vatis, suturis valde impressis ; basi prolong at a > obtusu ; aper* 

 tura ovali, postice angusta ; labro acuto ; tabio tenuissimo, 



Long. -105, long, spir '068, lat. '033 ; div. 20. 



=Leiostraca Irecta, Maz. Cat. in loco : non C. B. Ad. 



551. LEIOSTRACA PRODUCTA, n. sp. 



L. t. parva, albida, subfusiformi, marginibus spirts rectis; vert ire 

 acutiore, recto; anfr. norm, ix., planatis, suturis vix conx/ri- 

 cuis ; periphena satis rotundata ; basi rapide anyustata, postea 

 producta; apertura subrhomboiJea, axi antice acuta, anyulata; 

 labro acuto ; labio tenui. 



Long -123, long, spir '08, lat -046; div. 23. 



= Leiostraca 1 solitaria, Maz Cat., in loco: non C. B. Ad. 



This species is easily recognized by its very peculiar sharply- 

 pointed beak ; in shape like a young Kostellaria, without the canal. 



652. ANACHIS TVENIATA, Phil. 



Columbella taniata, Phil, in Zeit j. MnL 1846, no. 26 (non Ad. 

 & Rve. in Voy Samarang). 



Anachis Gaskoini, Cpr. in Maz. Cat p. 510. no. 652. 



Variat lineis spiralibus fuscis viii., quarum iii. in spira mon* 

 strantur ; maculis alternatis inter secundam et tertiam sitis. 

 Variat quoque maculis evanesceniibus. 



Hab. Callao (teste Gaakoin) ; Mazatlan (E. B. Philippi, Reigen); 

 Cape St. Lucas (Xantus) 



It appears that Mr. Gaskoin was not acquainted with Phi- 

 lippi's species, which had not then reached the Cumingian Collec- 

 tion ; as he pronounced M. Reigen's specimen to be new, and sug- 

 gested the specific name in the Mazatlan Catalogue. It would have 

 avoided a double synonymy, could the name tceniata have been re- 

 tamed for the Samarang shell, and Mr. Gaskom's for this. The 

 Cape St. Lucas shells vary as above inlicated. 



650. ?ANACHIS SERRATA, Cpr. 



Maz. Cat. no. 650, p. 509. Perfect specimens of this singular 

 species having been found at Cape St. Lucas by Mr. Xantus, the 

 diagnosis may be thus completed : 



Epidermide fimbnata, lirulas spirales eleganter decussante ; labri 

 denticulis variantibus, interdum subobsoletis. 



Long. -28. long, spir 15. lat -13; div. 40. 



With the sculpture and general aspect of a small Cantharus, it has 

 the mouth of an Anachis. The opercuJum, and therefore the generic 

 relations, are not yet known*. 



* The following additions and corrections may bo useful to the students of 

 the British Museum Catalogue : 



Species 181 Area multicostafa further differs from A.grandis in the epi- 

 dermis being soft and very finely hairy.
