276 Land and Freshwater Shells from the Shan States. [No. 4, 



ing from its nearest ally H. cycloplax. It appears to be a common 

 shell in ths Shan states, though not so in the Eastern Himalayas, but 

 all the specimens are dead shells. They agree well with the type, 

 though a trifle larger and more convex. 



3. Helix ansorinus, n. s. (MSS.) 



A very marked form, but all the shells dead ones. 

 The sculpture is very ornate and well marked. Shape somewhat as 

 in E. Peguensis. 1.20 X 0.60. 



4. H. delibrdta, B. 



5. H. 



6. H. 



7. H. 



8. H. (approaches _Z7. Guerini). 



9. JS. sanis, B. 



Though a trifle larger than the type, I can see no sufficient reason 

 for separating this from the Andaman shell. A few dead specimens 

 only are contained in the collection. 



10. E. infula, B. one or two specimens. 



11. H, attegia, B. one specimen. 



12. H. 



13. H. 



14. H. 



15. H. similaris, Fer. var. 



This shell is somewhat variable. It is usually banded, but occasion- 

 ally the band is obsolete. It tends to unite H. Zoroaster, Th. and 

 H. bolus, B., closely approaching the former, but being less depressed 

 and more tumid, though not so globose as the smaller sized H. bolus, 

 B. 0.75 X 0.40. Another variety occurs which might be ranked as a 

 large H. Zoroaster, Th., but it is not larger than the type of that shell, 

 bnt shows a tendency to approach H. delibrata, B. in form and expanded 

 peristome. 0.80 X 0.40. 



16. H. Oldhami, B. 



A little larger than the type which was from near Ava. 



17. H. Huttoni, Pf. 



A single specimen of this widely spread species was in the collection. 



18. H. Arahanensis, Th. A single specimen of this shell also 

 accompanied the last, a trifle flatter that the type.
