■^Ceritliiopsis in.sig'iiis a. sp. 1^1. VTI, fig. 18. 



Testa iniinma, elong'ato-pupoidea, corneo-albida., rufo 

 unibalteata; anfractus circiter 8^ convexiusculi, lente accres- 

 ceutes, seriebus tribus tuberculorum oniati ; series suprema 

 saturate i-ubra, mediana cgeteris minor ; aiifr. ultimus seriebus 

 quatuor cinctus ; apertura parva ; columella brevis, callo 

 crasso induta. Longit. 3"25 mm., diam. 1. 



Hab. — Port Shepstoiie (Burnup). 



A very small species, but well characterised by its striking 

 colouring. The tiibercles of the three series are joined by 

 longitudinal connections, so that the surface is, in fact, cancel- 

 lated. The median tubercles are much smaller than those of 

 the upper and lower rows. Quite distinct from C. p ni- 

 che 11a C. B. Adams, from Jamaica, which is somewhat 

 similarly coloured. 



"^ Cerithiopsis chapmaniana n. sp. PI. A^II, fig. 14. 



Testa elongata, turrita, alba, subpellucida, nitens ; an- 

 fractus 10, leviter convexi, costis longitudinalibus leviter 

 obliquis numerosis tenuibus lirisque spiralibus tribus, supra 

 costas granosis, cancellati, sutura profunda sejuncti ; anfr. 

 ultimus liris quatuor cinctus, infra concavus, la3vis, sed lineis 

 increnienti tenuissimis striatus ; apertura parva ; labrum 

 tenue ; columella in medio leviter arcuata, antice obliqua ; 

 canalis brevissimus, recurvus. Longit. 8 mm., diam. 2"75. 

 Apertura TVS mm. longa, l"2o lata. 



Hab. — Isezela (Miss Chapman). 



A pure white shell with three principal rows of granules 

 upon each whorl and sometimes a much finer row in the 

 spaces between. The longitudinal cost» are about twenty- 

 two in number, slender, a little oblique and slightly arcuate. 

 The apical whorls are broken away.
