MELANIA.— Plate XXXV. 



Irunned, strigis parvis undatis nigricantibiis obscure 

 pictd, anfraclibus novem ad decern, spiraliter lineari- 

 sulcatis, e suturis dense plicatis, sulcis plicisque in an- 

 fractibus ultimo etpenullimo, quibus obscure liratisgra- 

 datim evauidis ; aperturd ovatd, columella intorto-ef- 

 fusd. 



Morelet's Melania. Shell acuminately turreted, ful- 

 vous-brown, obscurely painted with small waved black 

 streaks, whorls nine to ten, spirally linearly grooved, 

 densely plicated from the sutures, grooves and plaits 

 gradually disappearing in the last and penultimate 

 whorls, which are obscurely ridged ; aperture ovate, 

 columella twistedly effused. 



Hab. New Caledonia. 



An interesting species from New Caledonia, partaking 

 curiously of the general typical character of those in- 

 habiting the Rio Branca and other rivers of Guiana. The 

 earlier whorls are eucircled with equidistant linear grooves 

 crossed by a dense puckering of folds descending concen- 

 trically from the suture; but in the penultimate whorl 

 they commence to disappear, and instead of linear grooves, 

 faintly raised ridges begin to be developed. I have much 

 pleasure in naming this species after its distinguished 

 owner, so favourably kuown to naturalists by his researches 

 in Central America. 



Fig. 240. (Mus. Morelet.) 



This shell, received from M. Morelet with the manuscript 

 name of M. macrospira, from New Caledonia, proves to be 

 identical with Mr. Hinds' M. aspirans, from the Feejee 

 Islands, described at Plate X. Sp. 53. 



Species 241. (Mus. Morelet.) 



Melania opiparis. Mel. testa pyramidali, solidimculd, 

 fulvo-olivaced, brunneo strigatd et variegatd, anfrac- 

 tibus octo ad novem ant pluribus, declivi-planulatis, 

 Icevigatis, ultimo ad basin liris brunneis funieulato ; 

 aperturd ovatd, superne attenuatd, inferne effusd, co- 

 lumella calloso-reflexd. 



The sumptuous Melania. Shell pyramidal, rather 

 solid, fulvous-olive, stained and variegated with 

 brown, whorls eight to nine or more, slopingly flat- 

 tened, smooth, the last corded with brown ridges at 

 the base ; aperture ovate, attenuated at the upper part, 

 effused at the lower, columella callously reflected. 



Morelet, Test. Nov. Amer. Cent, part ii. p. 23. n. 140. 



Hab. Guatemala. 



The chief characteristic of this specimen is its want of 

 sculpture. The species may possibly exist with some de- 

 velopment of corded ridges in the earlier whorls.
