rated from those that include the herbivorous forms. The two 

 suborders defined include very aberrant forms, which show 

 many points of resemblance to Mesozoic birds. Among the 

 more fragmentary remains belonging to this order, but not 

 included in the present classification, this resemblance appears 

 to be carried much further. 



The order Hallopoda, which I have here referred to the 

 Dinosauria, with doubt, differs from all the known members 

 of that group in having the hind feet especially adapted for 

 leaping, the metatarsals being half as long as the tibia, and 

 the calcaneum produced far backward. This difference in the 

 tarsus, however, is not greater than may be found in a single 

 order of Mammals, and is no more than might be expected in 

 a subclass of Heptiles. 



Among the families included in the present classification, I 

 have retained three named by Huxley (vScelidosauridte, Igua- 

 nodontidffi, and Megalosauridaj'^), although their limits as here 

 defined are somewhat different from those first given. The 

 suborder Compsognatha also was established by that author 

 in the same memoir, which contains all the more important 

 facts then known in regard to the Dinosauria. With the ex- 

 ception of the Hadrosauridaj, named by Cope, the other fami- 

 lies above described were established by the writer. 



The Amphisaurida3 and the Zanclodontida3, the most gene- 

 ralized families of the Dinosauria, are only known from the 

 Trias. The genus Di/strophceus, referred provisionally to the 

 Sauropoda, is likewise from deposits of that age. The typical 

 genera, however, of all the orders and suborders are Jurassic 

 forms ; and on these especially the present classification is 

 based. The Hadrosauridai are the only family confined to the 

 Cretaceous. Above this formation there appears to be at 

 present no satisfactory evidence of the existence of any Dino- 

 sauria. 



XII. — On a small Collection of Lepidoptera from Melhourne. 

 By Arthur G. Butler, F.L.y., F.Z.S., itc. 



The present series consists of ninety-one examples, some of 

 them unfortunately in very poor condition, forwarded to us 

 from Australia by Dr. T. P. Lucas. Notwithstanding that 

 not a few of the specimens are more or less worn or broken,
