The work of the naturalist should resemble in its method, no less than 

 in the devotion bestowed on it, that of Bees : — 



" Ergo ipsas quamvis augusti terminus aevi 

 Excipiat, neque enim plus septima ducitur a^stas 

 At genus immo-rtale manet, multos que per annos 

 Stat fortuna domus, et avi numerantur avoruin." 



Fam. ZONITID^. 

 Helicarion Flemingt, Pfr. 



This species is extremely abundant at Tandiani though not of quite so 

 large a size as specimens obtained by Stoliczka at Mari. My largest shell 

 measures diam. max. 36, min. 27 alt. 16, whereas a Mari shell measured 

 40 mills. 



To judge by Mr. Nevill's measurements (40 x 23 x 12) his measure- 

 ments are taken somewhat differently to mine. My ' diam. maj.' or length, 

 'min.' or breadth and 'alt.' (or axis of Mr. Nevill) are all measured at 

 right angles to each other and with a straight limbed measure, like a shoe- 

 maker's, not curved callipers, whence my ' alt.' or axis' is larger than 

 Mr. Nevill's, though the shell is a trifle smaller. 



H. Atjstenianus Nev. (Mollusca of the Yarkand mission). 



This species is scarce at Tandiani. The animal is furnished with a 

 large mucous pore behind, and carries a long linguiform process of the 

 mantle, capable of extension to the apex, and is one of those species which 

 though so provided does not possess a polished shell. The texture of the 

 shell (epidermis) is during life delicately sericeous, from the fine striation 

 of the epidermis. Mr. Nevill correctly describes it, as 'glossy,' that is like 

 silk. 



My largest specimen measure diam. maj. 16* min. 13 1, alt. 8 mills. 

 The animal is rather more depressed than H. Flemingi. 



H. Stoliczkantjs, Nev. (Yarkand mollusca). 



This species abounds on the north-east flanks of Sirban hill opposite 

 Damtour in a grove, frequented by picnic parties from Abbottabad. My 

 largest specimen measures ; 



Diam. maj. 275, min. 21, alt. 145 mills. 



The colour of the body whorl is greenish, of the earlier whorls rusty. 

 The shell is transversely rugous above, crossed by fine, above almost micros- 

 copic lines, giving it above a sericeous lustre ; beneath the shell is smooth 

 or sub-polite.
