measuring 22x6 mm., and three shells from Tenasserim, also 

 pale fuscous, but more solid in texture, composed of 11 whorls, 

 and measuring 25 x 6, 25 x 6''23, and 24 x 6-25 ram. respectively. 

 Finally, the late Miss Linter's collection, now in the Exeter 

 Museum, yielded two specimens from Phabougku, one of a 

 decided pink colour, with pale pink peristome, each of 11 whorls, 

 and measuring 21-5 x 6 mm. 



ClausUia r/ouldmna is closely allied to C. insiijnis, but may be 

 distinguished by its smaller size, smaller aperture, and lighter 

 colour, but more especially by the more acute apex, a feature by 

 which it may readily be separated from its ally. The 3 or 4 

 apical whorls also are usually white or pale corneous. The whorls 

 increase very slowly at iirst, then rather rapidly, the upper part 

 of the spire, consequently, being more concave ; the later whorls 

 are rather more convex than in insujnis. There are from four to 

 six palatal plicae, the lirst always long, the others vary in length 

 but are very short compai'atively ; they may be equal in length or 

 the second and fifth may be longer and the tiiird and fourth very 

 short, or they may gradually deci'ease in length. 



Fig. 108. — ClausUia goiildiaiia (Harvey collection). 



The shell figured in Conch. Ind. pi. 118, figs. 2 & 8, which has 

 been presented to the National collection by Mr. Harvey, is rather 

 short and ventricose ; it possesses 0| whorls, and measures 

 2:3-5x0 mm. This, according to Hanley and Theobald, may be 

 hisignis of Gould not of Pfeiffer, but I prefer to regard it as a 

 form of f/oiddlana. 



1 give a figure of this shell and a view of the inside of the 

 last whorl, with the palatal plicae in situ. The upper plica 

 (partly shown) is long, near to and parallel with the suture, the 

 second is stouter, its anterior extremity curving obliquely down- 

 Avards ; the third very short, oblique ; the fourth a trifle longer, 

 also oblique ; the fifth still longer, nearly vertical, its anterior 

 extremity giving off a slight ridge below near tlie subcolumellar 

 fold. 



Var. magna, nov. 



Differs from the type in being less ventricose. A specimen 

 from Moulmain, in the Theobald collection, possesses 13| whorls, 

 and measures 32 mm. in lene;th with a diameter of 0'5 mm.
