In the Royal Museum there are three jars, containing 

 five frogs and marked Bana ventricosa on the usual Drott- 

 ningholm labels. They are all Btifo vulgaris Daud., hut one 

 of the specimens, — a female with the belly distended by 

 ova — whieh probably has been dried, difFers considerably 

 from the usual habitus of Bitfo vulgaris, which caused Lin- 

 nteus to regard it as a new species. 



At a glanee we lind that this specimen must be the type 

 for Linnceus's Bana ventricosa. y^Corpus hypochondriis dila- 

 tatis tumidis-i. ^Bugce tres longitudinales elevati in tergo dorsi» 

 (The coccyx and the pelvis look like three sharp ridges). 

 •sSternum antice verruca magna prominensA (The sternum sticks 

 out in a sharp point). 



The other four specimens are all true Biifo vulgaris and 

 it seems un-likely that Linneeus should have regarded them 

 as belonging to this peculiar species, as they do not at all 

 agree with this one. 



Quensel also mentions one specimen only of Bana ventri- 

 cosa from Mus. Drottnh., but says that beside the Linnean 

 specimen there were three others with less prominent ster- 

 num, lighter colour and also covered with very distinct tu- 

 bercles, by which he evidently means the four specimens, 

 mentioned above (one of these specimens is so very small 

 that it must have been overlooked by Quensel). I cannot 

 explain, however, how these specimens have been provided 

 with the Drottningholm labels, marked Bana ventricosa, but it 

 is possible that they really are from this museum and have 

 there been named Bana Bnfo by Linneeus, though Swartz, 

 who labeled them afterwards, must then have done it incor- 

 rectly. This opinion is confirmed by the fact that there is 

 no specimen of Bana Bufo from Mus. Drottnh. to be found 

 in the R. Museum, though Linneeus records this species in 

 Mus. Äd. Frid. 



Length of the type specimen: body 97 mm., femur 33 mm., tibica 

 32 mm., tarsus with the 4th toe 55 mm.
