34:6 LAND AND FRESHWATER 



On page 284 ^fr. Benson gives an excellent description of the 

 animal : — " Ahjccpus, Gray. Tentacula duo raediocria, cylindracea, 

 apicibiis obtusis, oculos ad basin posteriorem ipsa gerentia ; oculi 

 integri, circulares, nigri minuti (quasi puncta), vix prominent es. 

 Pes brevis, ])ostice ultra testam non transiens, operculum testaceum 

 concaviusculum multispiratum, sursum ad dextram gerens." 



A. T7RNULA, Xo. 2589. Large variety. (Plate CLIII. fig. 2.) 



From Darjiling, I find among Blanford's specimens, one large 

 variety, and I have another in my own collection from Damsang, 

 Baling District, east of the Teesta, equally large ; it quite approaches 

 A. amphora in size ; the sutural tube is 2 mm. long, and the 

 eostulation close and regular. In form it has the elongate finer 

 spire of the smaller, much more numerous, typical shell and cannot 

 be separated. 



I have Dlorii.v urnula from many widely separated localities ; 

 a close examination of them all, presents much interesting variation 

 from the typical form found at Darjiling and Sikhim, which has 

 fine eostulation. 



In the Dafia Hills, in three specimens from Niosi Purbet 

 (Xo. 2600 B.M.), described further on as var. dajlaensis, I find 

 the sutural tube very short, only I'Q mm., compared with the 

 remarkably long one in typical iirnula from Darjiling. 



The same ditterence is found in two specimens from Toruputu 

 Peak, with fine eostulation. No. 2599 13. M. 



Examples from Brahmakund, No. 2532 B.M., are more globosely 

 tumid than type, with stronger peristome and stronger, more dis- 

 tant eostulation. 



From the Habiang Garo Hills, to S.W. of the Khasi Hills, 

 No. 2524 B.M., there is very fine close eostulation. 



Anghami Naga, No. 2529 B.M. 18 si)ecimens. Sutural tube 

 long, 2'4: mm., eostulation fine but mure distant. 



From Nougjinghi, No. 2526 B.M. a high Trigonometrical Station 

 on the north side of tne Jaintia Hills. Tlie general shape is 

 nearest to the Anghami shells. 



Only a single specimen occurs from llunipur, No. 2549 B.^I. 

 The apex is blunt, small and pink, and the eostulation very fine 

 indeed, and is the smallest variety I have seen.
