302 Mr. W. F. Kirby on the 



his paper before the Zoological Society, but for some reason 

 withdrew the name before his paper appeared in print, and 

 subsequently carefully avoided all reference to it. Under 

 these circumstances it is perhaps better not to hold Owen 

 responsible for Thylacomys, but to adopt it on the authority of 

 Blyth, by whom it was published as a perfectly valid name 

 one year prior to the appearance of Paragalia^ Gray. 



Thus, of the three names based on the rabbit-bandicoot 

 {Perameles lagoh's), Macrotis is preoccupied, Paragalia or 

 Peragah is antedated, and Thylacomys, the first tenable name 

 for the genus, should be adopted on the ground of priority. 



XXXII. — Notes on the Orthopterous Genus Phyllophora. 

 By W. F. KiRBY, F.L.S., F.E.S. 



[Plate VI.] 



The Phyllophorinse are a small subfamily of Mecopodidas 

 distinguished by the prothorax being produced backwards 

 triangularly into a large and more or less pointed hood, always 

 spinose, dentated, or crenulated on the sides. 



The number of species described is not large, and I do not 

 at present propose to break up the old genus Phyllophora, 

 but only to enumerate the described species, clearing up the 

 synonymy as far as possible and describing some new forms. 



It should be noted that most of the species, if not all, are 

 probably green when alive, unless the same species may be 

 either green or brown when living, as is the case in some 

 Orthoptera.
