 margin straight and very long posteriorly.

4 But a solitary specimen was met with belonging to tbis form, 

 which is more tumid in the centre than any of its allies, 0. in- 

 signis, Gould, etc. The non-continuity of the peristome may be 

 due to immaturity in the specimen found. The shape of the 

 mouth may also possibly be slightly modified in older examples, 

 but the general form doubtless remains the same, and is alone 

 sufficient to distinguish the species." (Blanford.) 



The shell figured in Conch . Ind. has been presented, with other 

 shells from the Hanley collection, to the British Museum by 

 Mr. Harvey ; it measures 22'5 x 6 mm. Three specimens in the 

 Theobald collection have a length of 23 mm. and a diameter of 

 6'5 mm., while the Beddome collection contains two specimens 

 measuring 23 x 6-5 mm. All are from the Arakan Hills. The 

 species tends to connect C. insignis with such forms as C. philip- 

 piana, C. ovata, and C. bulbus, but it is more acuminate and lacks 

 the very obtuse apex of the section Oospira, to which these species 

 belong. The upper parietal fold occurs on the outer edge of 

 the parietal margin of the peristome, the lower and the sub- 

 columellar folds only reach the inner edge ; there are six palatal 

 plicae, the upper long, the other five short.
