and three distinct, though opaque, stemmata. It approaches near 

 to Pierophylla K. the ovipositor being very similar in shape, but 

 much rougher : but its antennae afford a sufficient diagnostic from 

 that and any existing genus of Locustina, MacLeay. It appears 

 to form an osculant group between this tribe as explained above, 

 and the Grylli of Fabricius.

Art. III. Observations on the Structure of the throat in 

 the genus Anolis. B^ Thomas BeIjL, Esq. F.L.S. 



The peculiar structure of the throat in the genus Anolis, the 

 anatomical details of which I propose in this Notice to demon- 

 strate, has long been observed by naturalists, as far as regards the 

 external and obvious circumstances connected with it, but has 

 never, that I have been able to ascertain, been examined by dis- 

 section ; nor has the mechanism been pointed out, by which so 

 curious an effect is nroduced, as that which they have described.
