shallow water. This specimen was seen by Miss Tasker and 
identified as the same as the one herein described. It meas- 
ured eight inches in length. These specimens, coming as they 
do from lower levels and not from alpine localities, and from 
northern, in contrast with the warmer southern levels of most 
of the former discoveries, are interesting and hold out some 
prospects that a study of these creatures in their natural sur- 
roundings would throw light on the problem of the relation- 
ship of these peculiar larva to the amblystomas. The general 
appearance is shown in the accompanying drawings, which 
were made from the formalin specimen. The following dimen- 
sions were also taken from the specimen after preservation in 
formalin, but both were compared with the data from the fresh 
animal :
