Species 22. (Fig. a, b, Mus. Cuming. Fig. b, Mus. 

 V. d. Busch.) 



Melania coarctata. Mel. tenia tnrriculatd, ad basin 

 subclavatd, intense olivaced, anfractibus octo ad novem, 

 convexis, superue subexcavatis, striis incisis spiral iter 

 cingulatis, striis superioribus in anfractibus diiobus 

 ultimis obsoletis, longitudinaliter superficial iter plicalo-

The contracted Melania. Shell turriculated, some- 

 what club-shaped at the base, dark-olive, whorls 

 eight to nine, convex, slightly excavated round the 

 upper part, spirally encircled with engraved strife, 

 upper striae on the last two whorls obsolete, longi- 

 tudinally superficially plicately wrinkled ; aperture 

 small, rotundately ovate. 



Lamarck, Anim. sans vert. vol. viii. p. 430. 



Hab. Java, Philippine Islands ; Cuming. 



A dark, greenish-olive shell, encircled with conspicu- 

 ously cut, engraved strife, which in the last two whorls 

 appear only on the lower half. 



Species 23. (Mus. Cuming.) 



Melania Cumingii. Mel. testa subulato-turritd, nigra, 

 anfractibus octo ad novem, costd tumidd angulari spi- 

 ratiter coronatis, delude concavo-planatis, longitudina- 

 liter minute crispato-rugatis, striis spiralibus incisis 

 decussatis ; aperturd parviuseuld, ad basin lata, mar- 

 gine columellari calloso-appresso. 



Cuming's Melania. Shell subulately turreted, black, 

 whorls eight to nine, coronated with a spiral swollen 

 angular rib, then concavely flattened, longitudinally 

 minutely crisply wrinkled, decussated with spiral en- 

 graved striae ; aperture rather small, broad at the 

 base, columella!" margin callously appressed. 



Lea, Pro. Zool. Soc. 1850, p. 191. 



Hab. Island of Siquijor, Philippines (in very small 

 streams) ; Cuming. 



A strikingly characteristic species of the M. blatta type, 

 distinguished by having the whorls spirally surmounted 

 by a stout, cord-like marginal rib. 



diusculd, tenui, semipellucidd, cirescente vel olivaced, 

 punctis perpaucis rujis obscure maculatd, suturis albi- 

 dis, anfractibus tredecim ad quatuordecim, primis pau- 

 cis dense longitudinaliter costal is; aperturd parvius- 

 euld, ad basin lata, u/argiue columellari calloso-ap- 

 pressd. 



The glittering Melania. Shell acicular, somewhat 

 swollen at the base, thin, semitransparent, pale-green 

 or olive, obscurely sparingly red-dotted, sutures whit- 

 ish, whorls thirteen to fourteen, the first few closely 

 longitudinally ribbed ; aperture rather small, broad 

 at the base, columella!" margin callously appressed. 



Uab. Islands of Guimaras and Siquijor ; Cuming. 



These two shells, submitted by Mr. Cuming to Mr. 

 Lea, and pronounced by him to be a variety of his M. 

 aculeus {M. creituluta, Chemn.), appear to me to have a 

 specific assemblage of characters of their own. I cannot 

 bring them into any of the numerous varieties of that 

 species. They are of light semitransparent substance, 

 clavate towards the base, and have no transverse sculpture 

 whatever. The first few whorls are closely, minutely, 

 longitudinally ribbed. The sutures are whitish, and there 

 is a characteristic though obscure sprinkling of red 

 spots. 



Species 2-t. (Fig. a, b, Mus. Cuming.) 

 Melania fulgida. Mel. testa aciculari, ad basin lumi- 



Species 2a. (Mus. Cuming.) 



Melania pyramidalis. Mel. testa elongato-pyramidali, 

 solida, ponderosd, sordide olivaced, versus apiceiu. ru- 

 bella Jlammulatd, anfractibus duodecim ad tredecim, 

 convexo-planis, intention obscure spiraliter liratii ; 

 aperturd ovatd, ad basin producld et subeffusd. 



The pyramidal Melania. Shell elongately pyramidal, 

 solid, heavy, dull-olive, painted towards the apex 

 with reddish flames, whorls twelve to thirteen, con- 

 vexly flattened, sometimes obscurely spirally ridged ; 

 aperture ovate, produced and a litlle effused at the 

 base. 



Morelet, Test. Nov. Amer. Cent, part 1. p. 25. 



Hab. Upper Tabasco, Mexico. 



This bold solid species presents a characteristic step 

 to Mr. Lea's genus Pachycheilus, and should have been 

 figured along with that group. 



November, 1859.
