1889.] ON SOME SPECIES OF THE GENUS RHACOPHORUS. 27 
Little had been added to our knowledge of this curious form 
since the publication of the notice of it in Dresser’s ‘ Birds of Europe’ 
(iv. p. 383, pl. 242). 
The specimens in the Society’s collection had been purchased from 
M. Augéard, Préparateur Naturaliste, 22, Rue des Casernes, Oran, 
and were believed to have been captured in the south of the Province 
of Oran. 
In a recently published number of the ‘ Journal fiir Ornithologie’ 
(1888, p. 225) would also be found a notice of specimens of this 
Lark having been obtained by Dr. A. Koenig in the Tunisian Sahara 
in May 1887. 
Dr. Giinther, F.R.S., exhibited and made remarks on some fishes 
which had been dredged up by Mr. John Murray off the west coast 
of Scotland, and were not previously known to oceur in British 
waters, viz., Cottus lilljeborgit (Collett), Triglops murrayi, sp. n., 
Gadus esmarkii (Nilss.), Onus reinhardti (Collett), Fierasfer acus 
(Briinn.), Scopelus scoticus, sp. n., and Stomias ferox (Rubrdt. ).

1. On the Species of Rhacophorus confounded under the 
name of R. maculatus. By G. A. BouLENGER. 
[Received January 15, 1889.] 
A recent reinvestigation of the material in the British Museum has 
convinced me that several species have been confounded by me, as 
well as most of my predecessors in Indian herpetology, under the 
name of Rhacophorus (or Polypedates) maculatus. Apart from &. 
seavirgatus, Gravh.' (quadrilineatus, Wgm.), which is nothing but 
a colour-variety of the eastern form, R. /eucomystax, Gravh. (rugosus, 
D. & B.), two species have been described, upon the value of which 
herpetologists have been in doubts, viz. Polyp. eruciger, Blyth, and 
P. scutiger, Ptrs., both from Ceylon, The former was separated on 
account of its larger size and coloration. Nevill, who has recently 
taken up the matter again, distinguishes it from J. maculatus by its 
much larger size, stouter feet, and the uniform colouring of the 
hinder part of thighs, which never present any approach to the 
white or yellow spotting and marbling observable in R. macuiatus. 
Neither the characters pointed out vy Blyth nor those given by 
Nevill can serve to distinguish R. cruciger from the continental 
R. maculazes, if the latter be taken in the customary comprehensive 
sense ; and the total absence of white spotting on the thigh is so far 
from being constant that one of the specimens in the British Museum, 
1 Hylorana longipes, Fischer, of which the type specimen is now in the 
Museum, is another synonym of this variety.
