38 EXOTIC CONCHOLOGY. 



I have seen many specimens, but not one where the inner hp was developed on the upper part, 

 that is between the umbihcus and the top of the outer lip. In the varieties of B. Citrinus I have 

 seen, the inner lip is entire, much thickened and dilated over the umbilicus, which is thus hid in 

 mature age. 



ACHATINA MONILE. 



Testa subtilissime reticulata, albente, strigis undulatis, fasciisque transversis, castaneo- 

 maculatis, omata : anfractu basali subventricosa ; spiree productae anfractibus 

 2 ultimis approximatis : apice papilloso ; baai vix Integra. 



Shell very finely reticulated, with waved stripes and transverse bands of chesnut spots ; 

 basal volution subventricose : spire produced, the last whorls close and the tip papillary : base 

 nearly entire. Distinct from, though approximating to, Bulinus Zebra and Undatus. 



PHASIANELLA VENTRICOSA. 



Testa, ventricosa ; spirse anfractibus convexis, apice acuto ; aperturse vix efFusee, spireeque 

 longitudine eadem. 



Shell ventricose, spiral whorls convex, the tip acute ; aperture nearly effuse, as long as the 

 spire. Colour variable. 



P. INFLATA. 



Testa ventricosa, purpureo-fusca, strigis angulatis ornata, spiras anfractibus brevissimse 

 tribus modo manifestis. 



Shell ventricose, brownish purple with angular stripes, spire very short, of only thi-ee obvious 

 whorls. Near to but distinct from the last. Exclusive of the minute terminal whorl at the tip, 

 this species has but three, the preceding four, distinct volutions. 



MITRA NIVOSA. 



Testa ovato acuta, striis transversis, puncticulatis, exeavatis, nebulosa, punctis albis fuscis- 



que sparsis varia, maculis imparibus, fuscis bifasciata : labio crenulato. 

 Mitra Versicolor, Martyn, pi. 23. 



Shell ovate acute, with transverse striae and excavated punctures, clouded and variegated 

 with scattered dots of white and brown, and two bands of transverse unequal spots : outer lip 

 crenated. From New Holland and the Isles of the Pacific. 



MUREX PINNATUS. (PTERONOTUS). 



Tesia Candida, varicibus tribus, longitudinalibus, tortis ; fimbria tenui dilatata, radiata, 

 margine undulato ornatis, armata: spira produclaj canale elongate, arcuate; 

 labio exteriore denticulate.
