96. Neritina reticularis (pi. cxvi. f. 264-266), Soxoerby, 

 Conch. 111. f. 44. Sp. 51. Var. N. capillulata, Gould. 



N. testa subconica, lcevi, pallide fulva, rufescente, epidermide 

 tenui, subviridi induta, lineis angulatis transverse reticulata, ; spira 

 plerumque exsertiuscula, apice subcomplanato, anfractu ultimo, 

 supra suturam angulatim elevato, infra medium ventricoso ; aper- 

 tura subcontracts, labio externo superne dcclivo, infra medium 

 producto, columella tumida, margine sublsevigato. 



The shell varies considerably in form, but the upper part of the 

 last whorl is more or less obtusely angulated, so as to give a flat- 

 ness to the apex of the spire ; the apex i-? rather contracted at the 

 snture, but produced at the lower part ; the columella is very 

 gibbose. Altogether the shell is less gradually sloped than N. 

 reclivata, and the markings are less close and reticulated trans- 

 versely. The variety named N. capillulata (f. 266) is generally 

 shorter, and the markings less distinct. 



Calcutta. Var. N. capillulata, Burmah. 



97. Neritina lineolata (pi. cxii. f. 101, 102), Lam., Anim. 

 s. vert. Neritina, Sp. 14. Enc. Met., pi. 455. f. 4, a, b, Soicerby, 

 Conch. 111., f. 37. 



N. testa solida, subglobosa, laevi, epidermide subviridi induta, 

 lineis elongatis nigris flexuosis picta ; spira exsertiuscula, anfracti- 

 bus superne declivis, inferne ventricosis ; apertura albida, labio 

 externo antice rotimdato ; columella obbcpia, subgibbosa, obscuris- 

 sime subcrenulata. 



A thick, solid, subglobose, smooth shell, covered with an olive- 

 green epidermis ; the spire obtusely conical ; the upper part of 

 the whorls narrow, sloping, the lower part ventricose ; the colu ■ 

 mella is thickened, very obscurely crenulated at the inner margin, 

 very distinctly defined on the body-whorl. In the variety figured 

 in the Conch. Illust., the black, longitudinal, fluctuated lines are 

 narrower and more numerous than those in the other variety. 



98. Neritina sobrina (pi. cxii. f. 100), Recluz, MS. N. 

 Zebra, Sowerby, Conch. 111. f. 31, non Lamarck. 



N. testa N. lineolata simili, sed magis globosa, spira magis ob- 

 tusa ; labio interno minus distincto, labio externo intus incrassato. 



More globose than N. lineolata, with the spire less produced ; 

 the markings are broad and angulated.
