NOTES ON A SMALL COLLECTION OF AMPHIBIA FROM SUMBA. 


by 
Pror. Dr. P. N. VAN KAMPEN, 


(Zoölogisch Laboratorium, Leiden) 


and 
L. D. BRONGERSMA, 


(Zoölogisch Museum, Amsterdam). 


The present collection was brought back from Sumba by Dr. K. W. 
DAMMERMAN in 1925. Through different circumstances Prof. van Kampen who 
received the collection for identification could not finish this work and permitted 
the junior author to do this.— 

An annotated list of the species is given. One species and a variety are 
recorded for the first time from this island.

16 Trevpra Vor. XIII, Live. 1. 





During the last years this frog has been the subject of much discussion. 
The different characters on which R. verruculosa was separated from R. cancri- 
vora seem to be only of subspecific value. At the moment it is best to follow 
Dunn (l.c.) and take verruculosa as a variety of Rana cancrivora. 

Seven specimens from Laora, April 1925. 

In one specimen a vertebral band of the skin is bordered by broken-up 
ridges which are darkly coloured. This gives the impression of a light vertebral 
band. It is not white, however, as in specimens of cancrivora s. str. {in aleohol). 

One specimen and seven juv. from Kambera, March 1925. 

Two larvae from Kambera were referred to Rana verruculosa by the 
senior author. They agree very well with the description of larvae of Rana c. 
cancrivora (van Kampen l.c. p. 171). 


Rana papua Less. Š

Rana papua florensis, MERTENS, Abh. Senckenb. natf. Ges. 42, 1930, p. 225, pl. 5, 
fig. 5. 

Ten specimens from Kananggar, 700 meters above sea-level, May 1925. 

Eight specimens from Mao Marroe, 450 meters above sea-level, May 1925. 

This species was not yet recorded from the island. We can not follow MERTENS 
who describes specimens from the Lesser Sunda-isles as R. papua florensis. The 
difference between specimens from these islands and from New Guinea and 
Moluceas is only very slight. The tibiotarsal articulation reaches the nostril 
or beyond the tip of the snout. The characters given by Mertens (1930) to 
distinguish the sexes, proved to be quite sufficient. Two specimens were found 
to be females (eggs) the others were male. All the males had the flat. humeral 
gland and the tubercles on the back. As follows from the table with the 
measurement the length of the fore-limb is’ contained 1.6—1.5 x in the length 
of head and body in the two females. In the males the total length is 1.6—1.3 X 
the arm-length. 

Of the two females one is darkly coloured, the other one light grey above. 
Two males are also darkly coloured above. 

Two larvae were captured at Mao-Marroe. The largest measuring 56 millim. 
the second one 38 millim. total length. The distance between the eyes is equal 
to that between the nostrils and to the width of the mouth. In the first specimen 
the body is one time and a half as long as broad; the tail is four and half 
times as long as high and twice the body length.

In the second specimen the body is nearly twice as long as broad; the 
tail is one time and a half the body length and four times as long as high. 
The series of labial teeth are as in the first specimen, the inner series of the 
lower lip is hardly interrupted. 

These larvae agree very well with the description given by van KAMPEN 
(Le. p. 202). According to Mertens (1930) the series of labial teeth seem to 
vary in number to a great extent so that the difference of the larvae as 
described by Dunn and himself cannot be of specific value.
