Pondicherry being really from the island of Mauritius ;* and it is uncertain 

 that the forms reported from Cochin China, Siam, and Singapore are not 

 Assiminece. It is remarkable that the genus is almost entirely insular in its 

 known distribution, and that it is especially common in the Mascarene 

 Islands and in Polynesia. 



32. Paludomus teavancorica, Beddome, MS., Plate II, fig. 22. 

 Testa imperforata, ovato-conica, solidula, epidermide fused induta, siib 

 epiderinide alhida, fasciis fusco-purpureis flexuosis verticalibus ornata, 

 costis spiralihus suhconfertis circumdata, interspatiis glabris, striis incre- 

 menti inconspicuis. Spira conica, suhturrita, a^nce eroso, suturd impressd. 

 Anfr. superst. 3, convexi, ultimus dimidium testes superans. Aperfura sub- 

 verticalis, ovata, postice angulata, intiis ccerulescenti-albida, strig is flexuosis 

 confertis conspicuis. Peristoma rectum, margine externo acuto, colimellari 

 hasaliqiie albis, intus incrassatis, dilatatis. Operc. normaJe. Diam maj, 

 16, min. 13^, alt. 23 mm. {apice noii eroso ad 25) ; apert. 12 mm. longa^ 

 9 lata. 



Hab. Iu Travancore {H. Beddome). 



Shell imperforate, ovately conical, rather thick, covered with a dark- 

 brown epidermis ; beneath the e2:>idermis white, with narrow vertical, very 

 wavy dark purple stripes ; all the whorls spirally ribbed, the ribs rather 

 close together, with the interspaces smooth, the strife of growth being 

 inconspicuous. Spire conical, apex eroded (doubtless acute when perfect), 

 suture impressed. Whorls remaining 3 (probably in the perfect shell 5 or 

 6), convex, the last exceeding half the length of the shell. Aperture nearly 

 vertical, ovate, angulate at the posterior extremity, bluish white, with cou- 

 spicuous, close, vertical, wavy, deep purple bands within ; peristome in one 

 plane, the external margin sharp, the columellar and basal margins white, 

 thickened within, and dilated. Operculum normal. Major diameter 65 

 inch, minor 0'52, height (apex wanting) 0'9 (when perfect about an inch) ; 

 ajDcrture 0'5 high, 0'36 broad. 



In a young specimen of P. travancorica, there appears to be a ten- 

 dency to the development of minor parallel ribs between those forming the 

 spiral sculpture, and the latter are rather closer together near the suture.

 Moll. I. M. pt. i, p. 320. Hanley, Conch. Ind. Systematic list of Species, p. xiii, note 1, 

 ■whilst pointing out that the species is not Indian, states that it occurs in the Isle of 

 Bourhon. As he does not give his authority, the name of the island may have been 

 inserted by mistake for that of Mauritius, but it is possible that the form occurs, like 

 0. rubciis and two or three other species, in both islands.
