lying for a few years in heaps—when the men are lifting 
it for spreading on the roads. A dozen sent me from the 
roadsides in April were all young examples of the present 
species, measuring from 36 to 57 millimetres in length. 
The smaller ones had evidently just left the water. Oc- 
casionally, however, a few of the larvee appear to remain in 
the branchiate state long after the usual term. As already 
mentioned, two such were found in a deep pool on Luffness 
Links on Ist June 1894. “It is a pity,” writes Mr Boulenger, 
to whom one of them was sent for determination, “that you 
did not keep it alive, as it might have grown still and ripened 
its sexual organs whilst retaining its gills, thus reproducing 
the condition of the Axolotl, as is known to happen in J, 
cristata, M. alpestris, and M. vulgaris.” The length of this 
specimen was 52 mm. 
During March, April, and May of the present year, when 
large numbers were passing through my hands, I took the 
measurements of fifty males and fifty females, all supposed 
to be adult. Their total lengths in millimetres were as

These measurements include, in the case of the males, the 
caudal filament, which, on the average, would not be more 
179 mm. excluding caudal filament.
