Uiitersuchungen iiber die Giftwerkzeuge der Schlangen ; 

 Tubingen (1843-4); Researches on the Venom- organs of 

 Snakes, &c. 



The fangs of Deirodus scaber, Owen, the teeth and 

 poison-hags of Hydroplns pelamis, and the extraordinarily 

 long poison-gland of Naja rhombeatu, Schlegel, discovered 

 by Rheinhardtj are figured on two lithographic plates. The 

 question, as to whether the Snakes with sulcated teeth are 

 venomous or not, is not decided. 



J. Th. Rheinhardt has published, in the 10th vol. of the 

 Memoirs of the Danish Scientific Society, several new 

 Snakes. (Beskrivelse af Nogle nye Slangearter.) The paper 

 is accompanied with three lithographic plates, in which the 

 heads of the species described, and other characters are 

 exhibited. The diagnoses are as follows :
