Tbe abdomen was filled witb some bright green substance, 
which was emitted from the mouth when touched — apparently 
green paint nibbled off the shutters. 
The most nearly allied species to this which I have seen was 
obtained in Socotra, and is now in the British Museum. The 
breadth of the thorax is greater than in L. saccliarina , but the 
head is not concealed as in some species.

of the Peak. It also occurred on the mainland at Pernambuco 
iu similar localities. 
The chief peculiarity of this Lepisma is its very rounded back, 
resembling that of a Macliilis rather than that of a typical 
Lepisma. It is a small active species occurring singly, of a dark 
leaden-grey colour. The scales resemble those of L. saccliarina
