5. Plants and Animals. 
It can scarcely be doubtful that observations on the relations between 
plants and animals in desert regions would reveal many points of special 
interest. Unfortunately, as far as we could ascertain, there exist no 
publications on the subject. As to Aden itself, all we are able to say 
comes from the pen of Major Yerbury, who was kind enough to send 
us a short list of lame and their food plants. All the other interesting 
problems connected with pollination and dissemination, in which the ani- 
mal world plays such an important part, can in most cases only be a 
subject of conjecture for the present. Judging from various papers pub- 
lished on the zoology 1 of Aden it appears that most types of zoophilous 
plants may be represented in Aden : Melittophiloe , Micromelittophilee, 
Myiophilcey Micromyiophilce ) Sap r o my i op h i lee } Cantharophilce, Psycho - 
j vkila, and Sphingophilce.
