been recorded seems to have a cause peculiar 

 to itself. This may be either connected with 

 mating or it may have nothing to do with it, 

 as seems to be the case with the form described 

 as occurring about the university campus. 

 As a possible explanation of the movement 

 in the present case, it may be offered that it 

 is a preparation for winter. The adults live 

 over the winter under logs, leaves, etc. Their 

 eggs are laid in low, damp areas. Such lo- 

 calities are unfit for hibernation, and hence the 

 migration to more dry and protected localities.

RECENT ZOOPALEONTOLOGY. 



STEGOCEEAS AND STEEEOCEPHALUS. 



This review of the above-named genera of 

 dinosaurs, by the able paleontologist Franz 

 Baron Nopcsa (Centralblatt fiir Mineralogie, 

 etc., 1903, No. 8), is a highly important one 

 and is, at the same time, suggestive of our 

 limited knowledge of the Dinosauria generally 

 and of the great results to be looked for from 

 the study of this group of reptiles in the 

 future. These animals were recently described 

 by the writer from the Belly Eiver formation 

 of the Red Deer Eiver region. One has a 

 solid horn in the front part of the skull, the 

 other a solidly plated head. 



Nopcsa's interpretation of the Stegoceras 

 skull elements is noteworthy and accentuates 

 the necessity of having more material for 

 study before definite or final determinations 

 can be made. He comes to the conclusion 

 that the Stegoceras specimens that were sup- 

 posed to be from ' the median line of the head 

 in advance of the nasals ' * are to be inter- 

 preted rather as representing the frontal and 

 nasal elements of the skull. 



In support of this decision attention is 

 called to the frontal of Oamptosaurus 

 prestwicM, as figured by Hulke in the Quar- 

 terly Journal of the Geological Society for 

 1880. In this figure the strong, general 

 structural resemblance to the Stegoceras

specimens, particularly noticeable on the un- 

 der surface, is pointed out with emphasis. 

 Reference is also made to a similarly shaped, 

 but as yet undescribed, frontal of Mochlodon. 



According to the above interpretation, 

 Stegoceras brings to our notice an entirely 

 new type — a unicorn dinosaur, of especial in- 

 terest in that heretofore a form having an 

 unpaired horn springing from the fronto- 

 nasal region was unknown. 



It is still considered problematical whether 

 Stegoceras should be assigned to the Ceratop- 

 sidse or to the Stegosauridse. 



StereocephaluSj the second genus, is refer- 

 red by Nopcsa to the Acanthopholididse, and 

 is regarded as a new and important type cap- 

 able of throwing additional light on the modi- 

 fication of the skull of the Ceratopsidse. 



It is hoped that further contributions to 

 our knowledge of the Cretaceous dinosaurs 

 may be forthcoming from the pen of this sym- 

 pathetic writer and gifted observer.
