SYSTEMA reptilium auctore Leopoldo Fitzinger; Fasciculus 

 primus. Amblyglossse. Vindobonse, 1843. The author 

 gives an introductory general view of his System of the 

 Animal Kingdom, in which he classifies all animals, as far 

 as into orders, on the supposition that in each division one 

 system of organs must be specially developed. Thus, 

 according to him, the class of Reptiles is that in which the 

 function of generation, and at the same time the muscular 

 system, are especially developed, in opposition to that of the 

 Fishes in which nutrition, together with the osseous system, 

 would seem to be particularly developed. The further 

 division of the Reptiles, like that of the other Vertebrata, 

 is then proceeded with, according to the predominant 

 development of the five senses : (1) Touch : Rhizodonta, 

 with the orders Cetosauri, Loricata, and Ornithosauri ; (2) 

 Taste : Dipnoa, with the orders Ichthyodea, Hemibatrachia, 

 Batrachia ; (3) Smell : Testudinata, with the orders Oiaco- 

 poda, Steganopoda, Tylopoda ; (4) Hearing : Leptoglossre, 

 with the orders Ophidia, Hemisauri, and Sauri ; (5) Sight : 

 Amblyglossse, with the orders Ascalabot3, Humivagre, Den- 

 drobotae. The Crocodiles consequently' have been obliged 

 to part company with the Saurians, because the male has 

 five senses, and necessarily come under the tactile Reptiles 

 (Gefiihlsreptilien), which might now be associated (schwarmen)
