From Mus. Drott. there are two jars, labeled Lacerta 

 crocodilus, one of which contains two small specimens (230 

 and 240 mm. from the nose to the tip of the tail) of Caiman 

 sclerojjs (Schneider). In the other we find two ova with full- 

 grown foetus, the one of which puts out the head, proving that 

 it probably belongs to Crocodilus americanus Laur. It is clear 

 already by Linneeus's words: dociis in Asice, Äfricce, Americce 

 fervidisyy that the name, given by him, is a collective name. 

 According to Lönnberg ^ (1. c. p. 9) the type specimen for 

 the Linnean description in Amoenitates academicce {Amphibia 

 GijUenhoryiancC), in which paper Linneeus iirst describes La- 

 certa crocodilus, is a Caiman sclero])s, to which thus, accor- 

 ding to my opinion, the Linnean name must be given, and 

 this species then be called Caiman crocodilus (L.). 



Lacerta tigrina. 



Linnseus in Mus. Ad- Frid. I, p. 41. 



For reasons, not related, Linneeus uses this name only 

 in Mus. Ad. Frid. and changes it in Systema Naturce (Edi- 

 tio X, p. 201) to Lacerta monitor. It is evident, that Quensel 

 did not notice this alteration of names, as he says in his 

 catalogue that there is a specimen of Lacerta monitor to 

 be found in the collections from Museum Drottningholmense, 

 though there is no specimen of that species described in Mus. 

 Ad. Frid. As Quensel also does not state any specimen of 

 Lacerta tigrina as being present in the museum, it is clear 

 that the specimen of Lacerta monitor from Mus. Drottnh., 

 mentioned by Quensel, is Linnffius's type for Lacerta tigrina. 

 In the present collections of the Royal Museum there is no 

 lizard marked with the usual Drottningholm label: Lacerta 

 tigrina or Lacerta monitor, but we find a specimen labeled
