6. Gl. loxostoma. (Ad p. 202.) 



The typical specimens of this species are pale brownish or dull ferru- 

 ginous, and nearly smooth or obsoletely striated. Together with these a white, 

 solid variety occurs on the Khasi bills ; in form it tolerably agrees with 

 Blanford's fig. 65 (plate IX), some specimens are, however, still a little 

 thicker, and the transverse costulation on all the whorls is very distinct, 

 while the crenulation along the suture is generally not so coarse, as in typi- 

 cal loxostoma, though evidently stronger than in Asaluensis, which latter 

 also differs by a more slender shape and smaller aperture. Although the above 

 noticed form appears to be a well marked variety of loxostoma, the differeDces 

 do not seem to be constant, and both shells unquestionably are of the 

 same type. The crenulation on the two last whorls is often most regular, 

 each alternate rib somewhat projecting into the sutural impression. In other 

 specimens two ribs unite to a sutural tooth. The stronger or finer costula- 

 tion, or striation, of the whorls appears to depend upon the character of the 

 locality in which the specimens live. 



I have added a figure (6cl) of one of the shortest costulated varieties 

 from the Khasi hills. 



10. Cl. Gottldiana. (Ad p. 203.) 



This also is one of the most variable species, both in colour and form. 

 Young specimens are either brown or of a beautiful rosy tinge ; older shells, 

 after they become solidified, either retain the brown or pink colour, or the lip 

 becomes yellowish brown or perfectly white ; the 3-5 top-whorls are always 

 white. The form differs from fusiform to highly turreted, as may be indi- 

 cated by the following measurements — 



a. long 23, lat. 6, long, apert. 5"2, ej. lat. 4"2 mm. 



b. „ 28, „ 6 3, „ „ 6 2, „ „ 5" „ „ 



c. „ oJi, „ b 5, , f „ b" „ ,, 5. j, ,, 



All three specimens are from near Moulmain ; a is almost exactly identical with 

 Pfeiffer's original figure of the species; b and c are a white and a yellowish liped va- 

 riety from Mr. Theobald's collection ; c has an almost abnormally small aperture as 

 compared with the length of the shell. 



11 and 12. Cl. estsignis. (See also fig. 12a; ad p. 204). 



Mr. Blanford is of opinion that Pfeiffer's insignis is not the same as 

 Gould's, but that it is identical with the form figured by Hanley and Theobald 

 in the Conch. Iconica. 



There is undoubtedly a slight discrepancy between Gould's original 

 figure and description. He states the number of whorls to be 8 or 9, and the 

 apex ' mamillated,' while the figure shews it shortly pointed ; then again he 

 gives ' length 1 inch, breadth -§- of an inch.' The original figure (whether 

 enlarged or not, it is not stated) represents a shell of 28 mm. in length and 7 

 in thickness ; the second dimension is ; therefore, only one fourth of the total
