54 ZONITIDJE. 



The animal of E. baconi is said to have " only a small right lobe 

 (? shell-lobe) ; very small projections above the narrow compressed 

 mucous gland ; furrows of the sole of foot indistinct ; livid colour, 

 blackish on the mantle, round the pulmonary orifice " (Stoliczka, 

 quoted by Nevill, I. c.). 



[The best recorded series of the three species in question, with 

 accurate localities, is in the Indian Museum, Calcutta, and 

 Geoffrey Nevill keeps them distinct in his Hand-list. Taking 

 his H. baconi first, we cannot discard Benson's description of the 

 whorls being ornamented by a rufous band, although, as Blanford 

 says, this cannot be detected in the shell bearing this name in the 

 McAndrew (Benson's) Collection at Cambridge. This may be due 

 to bleaching. Benson's collection, after his death, did not receive 

 the care that it should have. " India " was substituted for Benson's 

 precise localities ; many of the types are not now to be found, and 

 so-called types are not in every case to be depended on, and now 

 require to be verified by specimens collected in the typical localities. 



I have before me a book from the Indian Museum Library, 

 " Drawings of the Animals of Helicidae executed under the Super- 

 intendence of the late Perd. Stoliczka." Among these is the water- 

 colour drawing of the shell and animal from life of a specimen 

 taken in the " Botanical Gardens, Calcutta ; got it also from 

 Moisraka " : marked " subdecussata ? " in Stolicza's handwriting 

 " jV. baconi, Bs.," entered afterwards, in that of G. Nevill. 



The shell is shown with a rufous band on the upper whorls, 

 which in the present connection is a most important point, because 

 no band of this sort is to be seen in Euplecta layardi and the 

 closely allied species from Ceylon. Stoliczka's description in this 

 book of this animal is as follows : " subdecussata ? " We must 

 remember these notes were slight, made for his own use, and not for 

 publication. " Only a small right lobe ; horn above gland small ; 

 livid coloured, blackish on the mantle round the pulmonary orifice ; 

 pedicles dark ; the furrows * on the sole indistinct." 



In Nevill's Hand-list, p. 35, no. 134, Nanina (Sitala ?) baconi, 

 Benson, we have not the above original description, but one 

 drawn up by Nevill, partly from the description, partly from the 

 drawing; and Blanford (see above) quotes Nevill's description, 

 which is incorrect and unmeaning in this sentence, " very small 

 projections above the narrow compressed mucous gland." Nevill 

 was looking at the figure, which is a very detailed drawing by the 

 native artist, size of life, and he did not make out that the said 

 projections were below the hooked gland (which is well seen with 

 a lens), and represent the termination of the foot behind on the 

 level of the sole. 



Nevill records this species (baconi) in the collection from 

 Benares (2), Moisraka and Calcutta (20), Chandbali (2), Kulu 

 Valley ? (1). From Benares, Moradabad is distant some 350 miles 

 further to the north-west, from Calcutta 650 miles. I may remark 

 here that these shells had never been compared with the type, the 



* [There are no furrows on the sole. Sole here, I suggest, refers to foot and 

 the furrows to the peripodial grooves.]
