22 L. G. ANDERSSON, CATAL. OF LINNEAN TYPE-SPECIMENS OF IIEPTILIA. 



All tbe forms belong to the species Pseudis paradoxa (L.), 

 and Liniiöeus shows that tlie anthors have been mistaken, 

 when considering this frog to be a larval form of a fisli. 



Testudo amboinensis. 



LinnfBus iu Mus. Ad. Frid. I, p. 49. Svst. Nat. Ed. X, p. 199 

 (iiamed Testudo geometrica). 



Tbe specimen of tbe tortoise Linneens described in Mus. 

 Ad. Frid. nnder tbe name of Testudo amboinensis is an Hyd- 

 raspis gibba (Schweigg.), as is proved by tbe present type- 

 specimen. It seems very curious that Linnseus in Systema 

 ISfatiirce puts tbis type, as well as tbe one be described in 

 Amoen. acad. Tom. I, N:o V, p. 139, as synonymous to bis 

 species Testudo geometrica., as it, according to Lönnberg (loc. 

 cit., p. 11), is quite certain that Linn8ens's type in Amoen. 

 acad. is tbe tortoise, now named Testudo geometrica L. (Bon- 

 lenger, Catalogne of tbe Cbelonians etc. in tbe Britisb Mu- 

 seum, 1889, p. 162), xvbicb diifers considerably from tbis type.^ 

 But it may be explained perbaps by tbe fact tbat Linneeus, 

 wben writing bis first desription, only bad a sbell, to examine, 

 for wbicb reason be did not know liow tbe feet were formed 

 in tbis type; furtber it is possible tbat Linnseus presumed 

 tbe great difference between tbe sbells tbemselves to depend 

 upon tbe fact tbat tbe specimen be described in Mus. Ad. 

 Frid. was so very young tbat it bad not received tbe cbarac- 

 teristic, tbick, and concentrically striated sbields, that were 

 to be found in tbe old sbell, described in Amoen. acad. Be- 

 sides, tbe epidermis remains only on tbe fiftb vertebral, partly 

 on bordering costals, and on most of tbe marginals, and, if 

 tbis want existed already at tbe tbime of Linnseus, tbis case 

 even would serve as an explanation bow it bappened tbat 

 Linneeus regarded tbese forms as being one species. 



Already Quensel noticed Linnfeus's mistake and records 

 in bis catalogne tbe Linnean specimen from Mus. Drottnb. by 

 tbe name Testudo orhicularis saying: »J/m5. Ad. Frid. p. 50. 

 Testudo amboinensis Imc pertinet. Exemplum ipsissimum a 

 Linnceo descriptum in spiritu vini serratur.y> Tbus, be was 

 of tbe opinion tbat tbis specimen was identical witb Linn8eus's 



1 When writing Mus. Ad. Frid, Linnseus evidentlj- did not consider 

 the two forms identical, as he there does not ref er to Amoen. Acad.
