ANCILLARIA MAURITIANA. Fig. 1 and 2. 



A. testd ovato-oblongd, ventricosd, castaneo-fulvd, margirubus validioribus ; spird brevissimd, superioribus anfracluum margini- 

 bits obtuse angulatis; ultimo anfractu balteo solitario et sulco lato supra varicem adjecto ; baltei margine superiore 

 levato; varies albo, glaberrimo, aperturd amplissimd, superne obtusiusculd, subtus effusd; labio externo superni

 Bab. in Insula S"- Mauritii. 



Desc. Shell ovately-oblong, ventricose, bright chesnut colour with darker margins; spire very short with the upper edges 

 of the volutions obtusely angulated ; last volution with a single belt, and a wide, but not deep groove above the columellar varix ; 

 belt with a raised upper edge ; varix white, very smooth ; aperture very large, rather obtuse at the upper, wide spreading, and 

 effuse at the lower extremity ; outer lip notched at the top, without any tooth on the lower edge. 



A few specimens of this new and very beautiful species have been brought to Europe lately from the Mauritius. Captain 

 Marryatt, R. N., has obligingly communicated the species to us : a perfectly white variety has also occurred.

 superne obtusd; labio ad basim edentulo, Icsvi ; long, l-fy, lat. $%, poll. ?

Desc. Shell oblong, cylindrical, ventricose, of a dark orange-brown ; with a very short, obtuse spire ; suture indistinct, 

 indicated by a rounded depression ; last volution with a single basal belt, and a groove above the columellar varix, which is white 

 and striated obliquely ; aperture very large, of a paler colour, obtuse at the upper part ; outer lip quite smooth and even, without 

 any projecting tooth at or near the base. 



A beautiful species and apparently very distinct from all those described by Swainson in the 36th number of the Journal of 

 Science, Literature and Arts. It differs from A. effusa, the only one with which, on account of its large aperture, it could be 

 confounded, in the following particulars; it is a much less slender shell, it is not banded with white, it has only a slight groove 

 above the varix of the columella ; it has only a single belt above the said groove, nor has it any tooth at the base of the outer lip. 



ANCILLARIA CANDIDA. Fig. 5 to 7. 



A. testd oblongd, elongatd, candidd; spird brevi, acuminata; suturd oblitd ; anfractu ultimo cingulis duobus basahbus, ei 

 sulco supra varicem instructo ; varice oblique striato; aperturd effusd, superne acuminata ; labio externo ad basim 

 obsoletissime unidentato ; long. 1-fa, lat. T %, poll.

Var. 2 da testa, pallide cinnamomea, dente basali valido. /. 7. Mus. nost. 



Desc. Shell oblong, elongated, slightly ventricose, yellowish white, sometimes with a bright rusty spot near the acumi- 

 nated point of the short spire; suture entirely hidden by the polished enamel, last volution having two impressed lines forming the 

 two oblique belts, the upper of these lines is the more strongly marked, and at its inferior termination on the edge of the shell 

 may generally be observed the indication of a small projecting tooth; a rather deep groove is placed immediately above the 

 obliquely striated columellar varix ; aperture effuse, acuminated at the superior extremity. 



This pretty little shell is commonly received with the Ceylon and Mauritius Boxes ; I had it also from Haynam ; two varieties 

 have come under my observation, the first is white with a very obsolete tooth near the lower edge of the outer lip; and the other is 

 of a delicate pale cinnamon colour, and has a distinct tooth ; it was communicated by Captain Marryatt, R. N.
