form of the lo moth (.4 iitomeris to) . The left side of the specimen 

 shows, in the coloration of the wings, head, thorax and legs, and 

 the structural characters of the antennas, the features of the nor- 

 mal male, while the corresponding right side shows the features 

 of the normal female, except the hind leg, which is like that of the 

 male. In shape and size, the abdomen is like that of the female, 

 while in color it is like that of the male, except that the under side 

 is dull brown, as in the female.

lEPARTMENT OF VERTEBRATE PALAEON- 

 TOLOGY. — -The preparation of the series of skel- 

 etons and bones representing the development of 

 the horse, provided for by the liberality of William 

 C. Whitney, Esq., is progressing satisfactorily. 

 The skeleton of the three-toed horse, Anchitherium, which was 

 discovered last season, has been mounted and placed on exhibi- 

 tion in the Hall of Fossil Vertebrates. This specimen has been 

 the means of determining positively the occurrence of this marsh- 

 living horse in this country, and has enabled Professor Osborn 

 and his assistants to clear up the doubtful relations of many 

 specimens which were obtained by Professors Leidy and Cope, 

 but which were too fragmentary to be classified satisfactorily. 

 Anchitherium was an animal about as large as a small Shetland 

 pony, and differed especially from the Plains horses by having 

 short-crowned teeth and by its broad-spreading three-toed feet 

 which enabled the animal to walk over soft ground without 

 sinking. 



The Museum has also secured recently from South Dakota a 

 considerable portion of an excellent specimen of Mesohippus 

 bairdi, which, together with material already in the collection, 

 will make possible the mounting of a skeleton showing this stage 

 in the development of the Horse. Mesohippus was about the 

 size of a sheep.
