48 LAND AND FRESHWATEK 



Microcystis steivartiana, MS., but never described. Nevill gives its 

 locality as Little Brother Andaman and Katchall, from De Roep- 

 storfF. No. 208 in the ' Hand-list,' from Batte Malve, Nevill thiuks 

 is the same species. 



SiTALA PHULONGENsis, G.-A. (Part II. p. 34, Plate X. fig. 4). 



The lingual ribbon of this species is of the tj'pe of Durgella 

 levicida, having a minute central tooth with a very great number of 

 similar multicuspid laterals ; the jaw almost straight. This is a 

 very remarkable common character, also occurring in Sitala infula 

 and S. aitegia (see Part II. pp. 26-30). This leads me to consider 

 the proper place of the genera Sitala and Kaliella to be after the 

 HelicarioninsB, and that it is quite possible for forms with close- 

 wound pyramidal shells to be not far distantly related to those that 

 are open-wound, depressed, and globose. 



Sitala rimicola, Bs., var. (Part II. p. 37, Plate IX. figs. 4-4 c). 



I have examples from near the Burrowli River, Durrang, Assam ; 

 Dunsiri Valley, North Cachar Hills, Munipur; the Anghami Naga 

 Hills, Lhota Naga Hills, and the Garo Hills. 



Sitala febrilis, W. T. & H. F. Blanford (Part II. p. 38, not 

 figured). 



There is a specimen in the late Mr. H. F. Blanford's collection 

 (in a letter, dated 11th October, 1891, received from him). 



Sitala ? balliana, G.-A. (Nevill, MS.) (Part ITI. p. 74, Plate XV. 

 fig. 2), is No. 193, Nanina {Microcystis), n. sp., of Nevill's ' Hand- 

 list,' p. 41 (type). 



Macrochlamys ? anon^, G.-A. (Part III. p. 91, Plate XIV. fig. 8), 

 is No. 163, n. sp., unnamed, of Nevill's ' Hand-list,' p. 38, 



Macrochlami-s? choinix (Part IV. p. 102, Plate XXII. figs. 6, 

 6 a.) 



" Animal very active ; throughout black, except sole of foot, 

 which is white " (Nevill). 



Macrochlamts choinix, var. qigantea, Nevill, MS. 



From South Andaman. In Nevill's emended ' Hand-list ' this is 

 catalogued as ? a distinct species. 



" Collected by F. A. de Roepstorff. Diam. 19-25 ; alt. 10-25 mm." 

 I have not seen an example of this shell. 



Macrochlamts peona, Nevill (Part IV. pp. 103 & 111, Plate 

 XXII. figs. 2, 2 a). 



Thanks <-o Lieut. F. Howard, R.E., for kindly collecting some 

 shells at Paurhi, in Gurhwal, N.W. Himalaya, I am able to supply 

 the description of the odontophore in this species. The animal is
