lived in the southern half of the continent. Europe stands next 

 to America in variety and number of these reptiles, large and 

 small." 



One interesting point with these animals is their relation to 

 the so-called " bird-tracks " of the Connecticut River sandstone, 

 which have been a " fruitful subject of discussion for half a cen- 

 tury or more,'' and Prof. Marsh considers it now evident " that 

 a dinosaurian reptile like Anchisaurus and its near allies must 

 have made footprints very similar to, if not identical with, 

 the * bird-tracks ' of this horizon." No zoologist can fail to find 

 the most absorbing interest in these gigantic and peculiar 

 reptiles, as, for instance, Atlantosaurus immanis, of which "the 

 femur is over 6 feet long, and this, with other portions of the 

 skeleton, indicates an animal about 70 or 80 feet in length," or 

 Laosaurus consors, estimated as having a height of about 4 feet, 

 with 8 feet in length. It is considered " that the animal was 

 bipedal in its usual locomotion on land," and when walking 

 upright it " seems probable that the animal would touch the 

 ground with its tail; but this is by no means certain." 



We have only alluded to matters of general interest in this 

 memoir, which is worthy of study by the zoologist, and is of the 

 greatest importance to the evolutionist. The structural details 

 are fully described, and eighty-five plates are given in illustration 

 of the remains of these vanished creatures. 



The Fauna of British India, including Ceylon and Burma : Moths. 

 Vol. IV. By Sir G. F. Hampson, Bart. Taylor & Francis. 

 1896. 



" With the present volume the first group of Indian Inverte- 

 brata included in the present series is completed." The magni- 

 tude of the work is shown by the fact that the four volumes of 

 Moths, with the appendix to the last volume, contain descrip- 

 tions of 5618 species regarded as valid, exclusive of races or 

 subspecies. 



These introductory remarks of Mr. W. T. Blanford, the 

 editor of the series, are necessary to appreciate this colossal 

 monograph, of which the volume under notice comprises only a 

 fourth and concluding part. It is but a few years back when
