■ioQ Mr. W. F. Kiiby on the 



Var. zonata, nov. 



Ornamented with a wide, ill-defined, and more or less 

 interrupted ochreous-brown zone, reaching from near the 

 suture to below the periphery. 



Uab. Same as the type. 



This handsome new species belongs to the group of 

 E. qucesita, Desh. It is, however, much smaller, much more 

 elevated in the spire, thinner in texture, more shining, and 

 has a narrower umbilicus. The dark zone of tlie variety is 

 evidently the result of the diffused colouring-matter of three 

 bands — one peripheral, one supra- and one infraperipheral — 

 which are faintly visible on holding the shell to the light. 



LIX. — Notes on the Neiiropterotis Famili/ Nemopteridse. 

 By W. F. KiRBY, F.L.S., F.E.S. 



Thirty-three sj^ecies of this small but very interesting- 

 family are enumerated in the present paper, of which the 

 Natural History Museum possesses fourteen, which I liave 

 distinguished by an asterisk (*). They are remarkable for the 

 great length of the hind %Yings, which take the form of long 

 slender tails. 



I have given the synonymy with tolerable completeness, 

 as the references are very scattered, and many of them occur 

 in old books not always easy of access. 



It is somewhat remarkable that, as in the Ascalaphidse, 

 the brightly coloured species are nearly all Mediterranean, 

 while those with hyaline fore wings mostly occur elsewhere.

The types of this genus are Nemoptera coa, L., as figured 

 by Coqnebert and Latreille. The latter figure has been 

 referred to N. h'penm's, but seems to possess the distinctive 

 characters of N. coa.
