1878.] FROM THE ANDAMAN ISLANDS. 81/ 



55. Litorina ventricosa, Philippi, Abbild. iii. pi. 6. fig. 19 ; 

 Reeve, Conch. Icon. fig. 93. 



Hab. Pulo Penang. 



L. novcEzealandia, Reeve, and L. melanacme, Smith, have a some- 

 what similar ventricose form, but differ in colour and the absence 

 of the granulation on the transverse ridges between the sulci. 



56. Cerithium (Vertagtjs) kochi, Philippi, Abbild. iii. pi. 1. 

 fig. 3 ; Conch. Icon. figs. 26 a, b. (Plate L. fig. 18.) 



Hab. East Africa, Philippines, Japan. 



The Andaman specimens are small, but agree very closely in de- 

 tail of sculpture with more typical ones, yet differ rather in colour. 

 They are pale horn-colour, with the granules, varices, and a band at 

 the top of the whorls whitish. Behind the varices they are blotched 

 with dark brown ; and their entire surface is irregularly dotted and 

 spotted with brown, and the transverse thread-like striae are also of 

 the same colour ; the liration below the middle of the body-whorl, 

 which is more prominent than the rest, is white, ornamented with 

 brown dots. 



57. Cerithium (Vertagtjs) turrttum, Sowerby, Thesaurus, 

 ii. pi. 180. fig. 101 ; Reeve, Conch. Icon. xv. fig. 58 ; Smith, Annals 

 & Mag. Nat. Hist. 1875, xvi. p. 106. (Plate L. fig. 19.) 



Hab. Philippines, Japan. 



The shells in the present collection are in colour and sculpture 

 exactly like those which I described in the Annals and Mag. Nat. 

 Hist,, from Japan, but a trifle smaller. 



58. Triphoris sculptus, Hinds, Voy. Sulphur, pi. 8. fig. 3. 

 Hab. Straits of Malacca (Hinds). 



59. TURRITELLA INFRACONSTRICTA. (Plate L. fig. 20.) 



Shell subulate, subturreted, brownish white, ornamented with 

 countless minute reddish-brown dots. Whorls about 20, somewhat 

 convex at the top and sides, and slopingly narrowed at the base, thus 

 making the width at the suture considerably less then a little distance 

 above it, transversely finely lirated ; liree varying in thickness, a few 

 being a trifle coarser than the rest, two especially — the upper, situated 

 very near the middle of the whorl, and the lower one at the broadest 

 part of it, being conspicuous and forming indistinct angles ; they are 

 all minutely dotted with brown. Last whorl excavated beneath, 

 finely lirated, and of a uniform brownish white or pale pink tint, 

 with a rather acute ridge circumscribing the base. Aperture irregu- 

 larly obliquely quadrate, of the same colour as the exterior ; but the 

 flattened base is coated with a thin pale rose-coloured enamel. Colu- 

 mella slightly oblique and a little arcuate. Length 50 millims., 

 diam. 12. 



This species, like most others in the genus, is chiefly distinguished 

 by the form of the whorl, the character of the markings, and the 

 spiral liration. The dottings on the ridges are very small, and are
