L. t. parva, albida, subfusiformi, marginibus spirce recfis; vertire 

 acutiore, recto; anfr. norm, is.., planatis, suturis vix conspi- 

 cuis ; peripheria satis rotundata ; basi rapide angustata, ]]ostea

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

 strantur ; maculis alternatis inter secundam et tertiam sitis. 

 Vanat quoque maculis evanescenlibus.

 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- 

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

 Cape St. Lucas shells vary as above iniicated. 



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 fimbriata, lirulas spirales eleganter decussante ; labri 

 denticulis nariantibus, interdum subobsolefis. 



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 operculum, 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 r/tuUicostata further differs from A.grandis in the epi- 

 dermis being soft and ver^ finely liairy.
