898 MOLLUSCA. 



M. iravadica, from Yaylaymaw, of three wliorls only, long. 30, diam. 17 mm. 



At the latter locality the species was found in great abundance by Dr. Ander- 

 son on the Second Expedition, as it was also on the Krst Expedition at Bham6 and 

 Manwyne ; the small specimens, so well figured by M. Brot,^ were from the latter 

 locality ; these specimens had been given in exchange by the Indian Museum to 

 the late Dr. Stoliczka, by whom they were sent to M. Landaner.

A rather young specimen of this very distinct species was well figured as above 

 by Reeve ; an adult specimen of the same species is figured in the ' Con. Indica, ' 

 pL Ixxii, fig. 3. It is a well characterized species, quite distinct from M. variabilis, 

 peguensis and gloriosa, and of these three it is nearest allied to the last. There 

 are specimens in the Indian Museum from Noungbenzik, in Pegu ; it was also 

 obtained plentifully at Mandalay on the First Expedition, and on the Second 

 Expedition at Myadoung.

About twelve specimens of this variety were obtained at Yaylaymaw. It can 

 be easily distinguished from the type form by its more developed sculpture ; it has 

 the same characteristic regular transverse ridges below the suture (four or five in 

 number), but in addition has throughout other interrupted transverse ridges, broader 

 than those near the suture and wider apart ; it has also numerous longitudinal 

 ribs, possessing a tendency at times to become obsolete (varying much in this 

 respect in individual specimens) ; these ribs commence at the termination of the 

 sutural row of regular transverse ridges, and are generally distinct only on the last 

 few whorls ; the columella is stained with a rich brown coloiu*.
