herbage along the banks of the Severn, the majority 

 being very large specimens ; near Hillditch Pool. 

 (N.B. — In my list in "Journ. Conch." the word 

 "Hillditch" has been spelt, as locally pronounced, 

 " Hillage." The present is the correct rendering.)

Limnaa peregra, Miill. Rivers Stour and Severn ; 

 Hillditch Pool ; Stinton Pool ; Rush Pool ; Stafford- 

 shire and Worcestershire Canal. 



Limnaa peregra var. convoluta, Wms. This

 the "Midland Naturalist" from a specimen collected 

 in Hillditch Pool. 



Limnaa peregra var. ovata, Drap. Hillditch 

 Pool. 



Li innaa peregra var ■. labiosa, Jeff. Hillditch Pool.

 was taken from the Staffordshire and Worcestershire

 bury Common (scarce) ; plentiful in a ditch in same 

 locality. Large specimens in a ditch in one of the 

 river meadows belonging to the "Coney Green" 

 farm. 



Limnaa palustris, Mull. A few specimens were 

 taken from a ditch in a field belonging to the 

 " Lickhill " farm. 



Ancylus oblongus, Lightfoot {=lacustris, Linn.). 

 On stones in Hillditch Pool ; not plentiful. 



Cyclostoma elegans, Miill. Mr. Kitching informs 

 me that several specimens have been taken near

Spharium corneum var. compressa, Gray. Hillditch 

 Pool. 



Spharium ovale, Fer. In my former list, this shell 

 was recorded as being found in a " pool in Shrawley 

 Wood (one dead specimen only)." This specimen 

 was thrown back into the pool, and I have more 

 than my doubts now whether I was not mistaken 

 in the diagnosis. The pool has been searched 

 thoroughly since, but no ovale were found. I am 

 resolved that what I found was in reality a young 

 specimen of S. corneum which approximated in shape 

 to S. ovale. Will those interested kindly make a 

 note of this correction ? they will greatly oblige the 

 writer by so doing.

In looking over the foregoing list two features will 

 strike the reader : the total absence of such other- 

 wise common species as Limnaa stagnalis and L. 

 truncatula ; and also the total absence of Planorbis 

 vortex, although its usual congener, P. spirorbis, is 

 comparatively abundant. 



THE EGGS OF INSECTS. 

 By P. L. Simmonds, F.L.S. 



MANY insects and their products have been 

 described and figured, from time to time, in 

 the long series of volumes of SeiENCE-GossiP, but 

 a separate consideration of the eggs of some insects 

 is not without interest. We utilise the eggs of 

 various fishes, birds, and reptiles, but those of 

 insects have comparatively small commercial value ; 

 only a few being taken any account of. Most insects 

 are oviparous. There are some eggs which are use-
