Of the Vertebrates, the Fishes, Amphibians and Reptiles, have 

 been referred, "vnthont exception, to living forms. 



The Birds, although belonging to existing Groups, include a large 

 number of extinct species, many of which were of gigantic size.* 



The Mammals were represented by a vast number of species, 

 many of which are remarkable for their great size. Not only were 

 there such colossal animals as the Megatherium and the Mammoth, 

 but many of the Carnivora of the earlier portion of the Period were 

 far larger than those now existing in any part of the world. 



Lastly, in formations belonging to the later portion of the Post 

 Pliocene,t or first division of this Period, have been discovered the 

 earliest remains of the highest Order of Mammals — Man — with whose 

 appearance, " the system of life in progress through the ages reached 

 " its completion, and the animal structure its highest perfection.";]:

NOTES ON SOME EXOTIC HEMIPTERA, WITH DESCEIPTIONS OF 

 NEW SPECIES.

Beyond the typical form and variety, described by Walker under 

 the name of the extremely divergent genus Atelocera, both of which I 

 have received from East Africa, I also possess two specimens of an 

 extreme form of the species collected by Mr. Cotterell at Nyassa, which 

 are of an almost uniform dark bluish-green without being mottled with 

 testaceous, as is the case with Walker's type although not so described. 

 The species has a constant character in the sub-triangular testaceous 

 spot on each lateral border of the pronotum. The species of this genus 

 appear generally to vary in this manner. The same thing may be seen 

 in H. scutellata, Dist., and H.picus, Pab. Mr. Walker has also added 

 to the already surcharged synonymy of the last species, as under — 



Halyomorpha picus, Pab. {Cimex picus),'Ea\)., E. S., 4, p. 115, 138 (1794) .
