1899.] And batbacSians from fokibn. 169 



This species, named after Mr. C. B. Eickett, is closely related to 

 R. latopalmata Blgr. (afghana Gthr.), from which it is easily 

 distinguished by the shorter fingers and the shorter hind limbs. 



7. Ehacophorus leucomystax Gravh, 



Although the largest specimen measures 50 niillim. from snout 

 to vent, the head is, as I have noticed before in Chinese specimens, 

 devoid of dermal ossification. The back of the thighs is whitish, 

 with a dark brown network. 



I seize this opportunity to observe that the Moupin Rliacopliorus 

 davicli Sauv. is not closely allied to this species. I examined the 

 types in the Paris Museum some years ago, and noted that the 

 fingers are one-third or one-fourth webbed and the inner meta- 

 tarsal tubercle is large, oval, somewhat more than half as long as its 

 distance from the tip of the inner toe. R. davicli is intermediate 

 between R. microtympanum and R. sMegelii. 



8. Ehacophoeus DENisrYSii Blanf. 



This fine Frog was described in 1881 from a specimen of 

 doubtful origin, obtained alive from a Chinese merchant at 

 Singapore and said to have originally come from China. The 

 type specimen, presented by Dr. Dennys to the Eaffles Museum, 

 was found, in bad condition, among the unnamed specimens of 

 that establishment a few years ago by Mr. S. S, Flower, who 

 brought the specimen over to London. I have been able to compare 

 it with a second specimen, from Foochow, presented to the British 

 Museum by Mr. C. B. Eickett in 1894. Mr. La Touche's Kuatun 

 collection contains three specimens. The following description is 

 taken from the five specimens now before me, varying in size 

 from 86 to 115 millim., measured from snout to vent, the species 

 being one of the largest of the genus : — 



Vomerine teeth on two strong, straight or slightly oblique 

 transverse ridges touching the inner front edge of the choanae 

 and separated by an interspace less than the Avidth of one of the 

 ridges. Head much depressed, broader than long, though some- 

 times very slightly ; snout rounded, truncate at the end and 

 slanting from the nostrils to the edge of the mouth, its length 

 equal to the diameter of the orbit ; canthus rostralis strong ; 

 loreal region concave ; nostril nearer the end of the snout than 

 the eye ; interorbital space broader than the upper eyehd ; 

 tympanum very distinct, measuring two thirds to three fourths 

 the diameter of the eye. Fingers with very large disks, broadly 

 webbed, the web reaching or nearly reaching the disks between the 

 two outer, also reaching the disk on the outer side of the second 

 finger, but only the penultimate phalanx on the inner side of the 

 second and third ; a large, compressed, crescentic tubercle 

 (rudimentary pollex) at the base of the inner finger, which is 

 much shorter, and has a much smaller distal expansion, than the 

 second ; the largest digital disks nearly equalling the tympanum in 

 size. Toes moderately elongate, webbed to the disks, which are
