MEL ANIA. 



Plate XXXI. 



Species 204. (Mus. Cuming.) 



Melania variabilis. Mel. testa subulato-turritd, vires- 

 cente-olivaced, anfractibus spiraliter subobsolete funi- 

 culatis, superne concavo-angulatls, delude plicato-cos- 

 tatis, cost is in anfractibus ultimo el penultimo ad un- 

 guium subacute luberculatls, versus aperturam grada- 

 thn evanidls ; aperturd ovatd, columella calloso-effusd. 



The variable Melania. Shell subulately turreted, 

 greenish-olive, whorls spirally obsolete])- corded, con- 

 cavely angled round the upper part, then plicately 

 ribbed, ribs of the penultimate and ultimate whorls 

 rather sharply tubercled on the angle, gradually fading 

 towards the aperture ; aperture ovate, columella cal- 

 lously effused. 



Benson, Journ. Asiatic Soc. 1S35. 



Melania Indica, Eydoux and Souleyet. 



Hub. India. 



The plicated ribs of this species do not commence to be 

 sharply tubercled until the penultimate whorl. 



Species 205. (Mus. Hamilton.) 



Melania circumstriata. Mel. testa pyramiddli-turritd, 



pohjgond, fusco-nigrd, anfractibus declivi-augulatls, 

 oblique varicoso-costatis, slriis elevalis cequidistantlbus 

 undique spiraliter funiculalis ; aperturd ovatd, calloso- 

 effusd. 



The stri^-encircled Melania. Shell pyramidally 

 turreted, many-angled, brownish-black, whorls slant- 

 ingly flattened, obliquely varicosely ribbed, spirally 

 corded throughout with equidistant raised striae ; 

 aperture ovate, callously effused. 



Metcalfe, Pro. Zool. Soc. 1851, p. 73. 



Hab. Borneo. 



At Plate IV. I described and figured for this species a 

 shell which Mr. Cuming had assigned to it in his collec- 

 tion, with the remark that it might be pronounced to be 

 the Borneo representative of the Philippine M. asperata. 

 Since then I have been fortunate enough to obtain the 

 original types in the collection of Mr. Hamilton; and I 

 have little doubt that Mr. Cuming's specimen is really a 

 Philippine M. asperata. It will be perceived by the ac- 

 companying figures of the true M. cirenmcincia in different 

 stages of growth, that it is a very distinct and excellent 

 species. The shell is more sharply pyramidal, and of a 

 polygonal form, owing to the oblique varix-like ribs which 

 emerge from the sutures (not from the angle of a contracted 

 concavity), and the encircling cords are more defined. 



Species 20G. (Mus. Cuming.) 



Melania rubicunda. Mel. testa turriaulatd, solidius- 

 cula, rufescente-olivaced, anfractibus septem ad octo, 

 rolundatis, lavibus, vel sub lenle minutissime strialis ; 

 aperturd ovatd, parviusculd , columella' subcallosd. 

 The ruddy Melania. Shell turriculate, rather solid, 

 rufous-olive, whorls seven to eight, rounded, smooth 

 or very minutely striated beneath the lens ; aperture 

 ovate, rather small, columella slightly callous. 



Hab. ? 



A small species of the Packycheilus section, which can- 

 not be referred to any of those previously described. 



Species 207. (Mus. Cuming.) 



Melania Brookei. Mel. testa obeso-lurritd, brunneo- 

 nigricante, anfractibus lavibus vel obscure spiraliter 

 striatis, superne concavis, delude obtuse angulatis, ad 

 unguium plicato-tuberculalis, fiiberculis distantibus ; 

 aperturd ovatd, columella calloso-effusd. 



Brooke's Melania. Shell stoutly turreted, brown- 

 black, whorls smooth or obscurely spirally striated, 

 concave round the upper part, then obtusely angled, 

 plicately tubercled on the angle, tubercles distant ; 

 aperture ovate, columella callously effused. 



Hab. Borneo ; Lieut. Taylor. 



This fine species, which I dedicate to Sir James Brooke, 

 the late Rajah of Sarawak, is characterized by a remark- 

 ably bold design of form and sculpture. 



Species 208. (Mus. V. d. Busch.) 

 Melania sparsinodosa. Mel. testa subpyramidali-tur- 

 ritd, fusco-nigrd, anfractibus declivi-convexis, spiraliter 

 striato-fuuiculatis, superne coucaviusculis, delude hie 

 i/lic obsolete luberculato-nodosis ; aperturd ovatd, co- 

 lumella calloso-effusd, lutescente. 

 The sparingly-knotted Melania. Shell somewhat 

 pyramidally turreted, brown-black, whorls slopingly 

 convex, spirally striately corded, rather concave round 

 the upper part, then here and there obsoletely tubci- 

 cularlv noduled ; aperture ovate, columella callously 

 effused, yellowish. 

 Von dem Busch, Malak. Blitter, 1858, vol. v. p. 36. 

 Hab. Borneo. 



Of a more slender pyramidal form than the preceding 

 species, less concave round the upper part of the whorls, 

 and only obscurely noduled here and there. It remains 

 for future research to determine whether these two appa- 

 rently distinct forms may not be connected by intermediate 

 varieties. 



May, 1860.
