EANA. 307 



and a somewhat more slender habit, resulting in a 

 certain resemblance to Bana agilis, with which it also 

 often agrees in the absence of any but small red spots 

 on the belly. 



The var. bosniensis, recently established by Werner 

 (' Rept. Amph. Oesterr.,' p. 92) on a single male 

 specimen from Travnik, Bosnia, is, in my opinion, not 

 entitled to stand. Thanks to Dr. Werner's courtesy, 

 I have examined the type, and find the pelvis to 

 be broken, which accounts for the shortness of the 

 body ; hence the tibio-tarsal articulation of the hind 

 limb reaches a little beyond the tip of the snout. The 

 specimen measures 71 mm. from snout to vent ; fore 

 limb 49 mm. ; tibia 42 mm. 



The var. longipes of F. Miiller — of which the type, 

 from Oberweiler, between Mullheim and Badenweiler, 

 Baden, has been entrusted to me by Mr. Schenkel, 

 the curator of the Basle Museum — is based on a 

 somewhat long-legged individual of the common frog, 

 in which the tibio-tarsal articulation reaches exactly 

 the tip of the snout, — not beyond, as stated in the 

 original description. The specimen, a female, measures 

 55 mm. from snout to vent ; fore limb 36 mm. ; tibia 

 30 mm. C. Koch's var. gracilis is no doubt founded 

 on similar examples, which seem to predominate on 

 the southern slopes of the Alps, and have been de- 

 scribed by Heron-Royer as a distinct sub-species, Bana 

 fusca honnorati, from the Basses-Alpes. The larval 

 characters adduced in support of the establishment of 

 the latter form have since proved to be as unreliable 

 as those derived from the perfect animal. 



Skeleton. — Fronto-parietals broad and flat, about 

 twice and one-third to twice and three-fourths as long 

 as broad. Nasals small, separated from each other, 

 with strongly concave posterior border. Upper part 

 of ethmoid rounded or obtusely pointed in front. 

 Zygomatic process of squamosal shorter than the 

 posterior process. Occipital condyles behind the line 

 connecting the articular extremities of the upper jaw.
