disc, spot hardly distinguishable from the ground- 

 colour. J something like C. aurora J , but smaller 

 and much duller in colour. The nervures are 

 black. U.s. somewhat as in C. thisoa, but the dark 

 green of that species is replaced by a light 

 yellowish-green. The sub-marginal spots on f.w. 

 are either entirely wanting or very slight. Disc, 

 spot h.w. small and with a very faint edging of red. 

 Antennae very dull red ; fringes of all the wings 

 narrow and inconspicuous. The above description 

 is from a pair sent to me by the late Dr. Staudinger 

 from the " Transbaical." 



HAB. Transbaical. Northern Siberia on the 

 Jenisei and Vilui Eivers (Elw.), Pokrofka Amur 

 (E. and H.). 



17. C. felderi Gr.-Gr. 



22—25 mm. 



c? somewhat paler than C. hecla. F.w. disc, 

 spot rounded, marginal border narrow with yellow 

 rays at apex f.w. H.w. with a very narrow border 

 and a row of lightish spots internal to the border, 

 as in C. myrmidone, etc. Disc, spot faint. U.s. 

 h.w. the disc, spot is very small rose-red, and sur- 

 rounded by a broad edge of reddish-brown. De- 

 scribed from specimens in Leech's Collection, in 

 which only the $ is represented. 



Hab. Sinin Alps, Central Asia.

Winkton, Ringwood, Tuckton (C. A.), Itchin at 



Winchester (C. F. A.). 

 Vivipara vivipara Linn. Itchin at Winchester 



(F. J.). 

 Vivipara conteeta Millet. Itchin at Winchester 



(F J.). 

 Valvata piseinalis Mull. Fairly abundant 



throughout the county. 

 Valvata cristata Mull. North Hants, common 



(H. P. F.) ; rivers Avon and Stour (C. A.). 

 Pomatias reflexus Linn. North Hants, common 



(H. P. F.) ; generally distributed in Isle of 



Wight (A. L.). Var. pallida Moq. ; somewhat 



rare in Isle of Wight (A. L.). 

 Neritina fluviatilis Linn. Itchin at Winchester 



(F. J.) ; abundant in rivers Avon and Stour 



with great variety of markings (C. A.). Var. 



cerina Colb., about 4 per cent, of the whole

TJnio tumidus Retz. Basingstoke Canal (coll. H. C. 

 Leslie, in Hartley Inst.). This species has 

 evidently made its way into the county along 

 the canal. There is no record of any example of 

 the genus occurring in the district, either living 

 or in the post-pliocene deposits, if we except 

 fragments recorded by Bristow from the Tot- 

 lands Bay deposit. These fragments, we are in- 

 clined to think, were more likely portions of 

 Anodonta. 



Anodonta eygnea Linn. River Stour at Tuckton 

 Bridge, generally undersized, occasionally at- 

 taining five inches ; at Beaulieu, six inches 

 (C. A.) ; near Havant (C. E. W.). There are very 

 large specimens in Alton Museum from Woolmer 

 Forest (J. T. C).

 all suitable places (C. A.) ; Sandown, Isle of

 also (A. L.).

 breadth 10 mm. ; Ringwood, Brockenhurst, 

 abundant and fine (C. A.).

 Aid., Sandown (A. L.) ; var. lienslowana Shepp.,

 Stom at Christchmch (C. A.).

 Avon and Stour at Christchurch (C. A.) ; North 

 Hants (H. P. F.) ; colony in a pond at Hamble- 

 don (C. S. Coles).

In addition to the foregoing the following 

 species, in fossil or sub-fossil condition, have been 

 met with in alluvial deposits : — 



Vertigo substriata Jeff. Test Valley. 



Vertigo pusilla Mull. Test and Itchin Valleys.
