70 THE SCOTTISH NATURALIST 



through the writer's hands during the past three years, but 

 not a single specimen that could be referred to this species 

 has been seen. 



It is a striking form, and easily distinguished from 

 T. pusillus, Brandt, or T. stebbingi, Patience, by the shape of 

 the cephalon, the antennae, and the telson, as well as by its 

 general colour, a dark reddish-brown marbled with white. 

 Like T. pygmceiiS) G. O. Sars, it has a 3-jointed flagellum of 

 the antenna, but its telson is terminally obtusely rounded 

 and not truncate as in T. pygmceus. 



For the specimens here recorded I am indebted to the 

 kindness of Miss y. J. Jardine, who collected them in a 

 walled garden at Hunter's Quay, Argyllshire. There are no 

 greenhouses anywhere in the neighbourhood. 



Limnaea glabra, Hyalinia lucida, and Zonitoides nitidus 

 in Stirlingshire. Mr George Nelson has been successful in 

 adding these three species to the authenticated list for Stirlingshire. 

 Of Limncea glabra he found several, adult and young, in a roadside 

 pool on the Drum Road, Falkirk, in October 191 7 ; a single Hyalinia 

 lucida was picked up on the bank of the Union Canal near Falkirk 

 on the 26th of the same month ; and several Zonitoides nitidus were 

 found in Carron Glen on the 3rd of November, along with several 

 Vitrina pellucida, several Hyalinia cellaria, a few H nitidula, a few 

 dead H crystallina, several Pyramidula rotundata, one very 

 juvenile Hygromia hispida, three dead Zua lubrica, and a few 

 Helix hortensis var. lutea 12345 and 1(23)45. Ancylus fluviatilis 

 was plentiful the same day in the Garvald Burn in Carron Glen. 

 The occurrence of L. glabra I look upon as not only a most interest- 

 ing but a highly important addition to our knowledge, as we have 

 previously only had it authenticated from three Scottish vice-counties, 

 viz. 77 Lanarkshire, 83 Edinburghshire, and 89 Perthshire North.
