3. On some Dragonflies obtained by Mr. and Mrs. Lort 
Phillips in Somali-land. By W. F. Krrsy, F.L.S.,

[Received April 21, 1896.] 
Two days were devoted by Mr. and Mrs. Lort Phillips during 
their stay in Somali-land to the capture of Dragonflies, and 
examples of six species were obtained. Five of these belong to 
the Libelluline, and one to the Aschnine ; and though three are 
common and well-known species, I am able to describe the others, 
which I refer provisionally to the genus Orihetrwm, as apparently 
new to science. It is, however, somewhat to be regretted that I 
have only single specimens before me at present.
