N. testa iV. Zebra simili, sed anfractibus prope suturam depressis; 

 columella complanata, castanea. 



Resembling N. Zebra, but with the whorls rather depressed 

 near the suture, and the columella rather flat, and of a chestnut 

 colour.

N. testa N. Zebrce simillima, sed magis conica, spira magis ex- 

 serta, labio interno tumido, carneolo. 



Eesembling N. Zebra, but with the spire more produced, 

 and the inner lip more tumid. The variety (f. 91) named N. 

 Roysslana, Recluz, and figured in the Conchological Illustrations 

 as N. strigilata var., is smaller, and has the black markings very 

 small and angulated.

108. Nemtina semiconica (pi. cxii. f. 116), Lam., Anim. s. 

 vert. Sow., Conch. 111. f. 23. 



N. testfi N. Zebrce simili, sed magis conica, solidiore, labio in- 

 terno tumido, carneolo ; N. tnrritce simih, sed inag\s ovali, maculis 

 nigris in fasciis tribus picta. 



Tliis is so distinctly recognizable as a species of Lamarck, that 

 we do not push our scruples to the extreme against admitting a 

 specification which has so little beyond arrangement of colour to 

 sustain it. The shell is like N. turrita, but rather more solid, 

 and has the slope of the spire more gradual. The three bands of 

 dull grey are marked by angular black spots. 



Banks of the Ganges, Calcutta. 



109. Neritina pulchra (pi. cxii. f. 89, 90), Sow., Conch. 

 111. f. 59. 



N. testa N. Zebrce simili, sed columella sub complanata, vix 

 crenulata, fulvo tincta, epidermide translucida, rubro et nigro 

 varie picta. 



The columella is flatfish, scarcely crenulated, with a touch of 

 yellowish colour-. Under the somewhat transparent epidermis 

 may be seen a broad-meshed reticulation of red in two bands and 

 black in three.
