NATURAL SCIENCES OF PHILADELPHIA. 139 



This species is more slender in form than the others of the genus, and ex- 

 hibits a fuller palmaiion of the feet ; it does not difl'er more from the species 

 of Hoplobatrachus Pet. than the Rana; do among themselves. One spec. 

 (282) has the whole upper surface of the head, and a broad vertebral band 

 yellow. Of the types are two specimens (No. 283) in Museum Comparative 

 Zoology, Cambridge, all from Madagascar, presented to Prof. Agassiz by G 

 W. Goodhue. 



ToMOPTERNA POROSA Cope, sp. nov. 



Toes nearly completely webbed, 2-3 phalanges of the fourth toe free. Muz- 

 zle obtuse ovate from above, decurved in profile, as long as diameter of eye- 

 slit. Top of front and muzzle plane, canthus distinct, contracted, obtuse 

 loreal region with a longitudinal concavity. Tympanum round, nearly as 

 large as eye, distinct From orbit to maxillary border '66 diameter tympan- 

 um ; lip rather prominent below orbit. Vomerine teeth in two fasciculi op- 

 posite middle or hind margin of choanae, nearer each other than margin. 

 Choanaj smaller than the large ostia. 



Fingers with very small web at base, thumb longer than second, equal 

 fourth. Tarsus of extended limb beyond end muzzle ; heel to front of orbit. 

 Tarsus 2-3 times in longest toe. Cuneiform shovel 2-56 times in tarsus.

A glandular dermal fold from above tympanum to above groin on each 

 side ; the greater part of the eyelid glandular and covered with pores. A 

 glandular fold from angle mouth to behind above axilla. No tarsal folds. 



Color above brown, with dark-gray shades ; in one specimen an imperfect 

 pale-gray vertebral line. Under surfaces white, sides coarsely and hand- 

 somely marbled with brown and white below and gray above. Head dark- 

 brown, a pale line on the lip, a slight margin to lower lip. Femur brown 

 with pale marblings. 



This species is abundantly different from those hitherto known, and seems 

 to indicate that the genus Hoplobatrachus Peters is less distinct from Tomop- 

 terna than hitherto supposed. 



Three specimens (No. 305), Agassiz' Mus. Compar. Zoology, Cambridge, 

 Mass. From Kanagawa, Japan. From Dr. Jas. T. Gulick. 



Hylorana leptoglossa Cope, sp. nov. 



This species is most nearly allied to the H. temporalis Grinther of Cey- 

 lon. The points of difference are italicised in the following description : 



Hind limbs as in H. t e ni p o r a 1 i s, and the fourth toe is only -33 longer 

 than the third and fifth. Two well marked metatarsal tubercles. Vomerine 

 teeth in two very short oblique rows commencing opposite the posterior 

 margins of the choanse and directed backwards ; they are about as far from 

 each other as from choante. Tongue narrow, not filling rami of jaws. Tym- 

 patuim as large as eye ; latter contained 1-5 times in length of muzzle, extending 

 beyond nostril. A heavy glandular dorsolateral fold, separated by a groove 

 from another interrupted one beloiv it. A deep groove from axilla to near groin. 

 A short glandular fold from angle of mouth. Muzzle fiat tened acuminate at the end. 

 Heel of hind limb to front of orbit. Fourth toe more than half length head, 

 and body; no dermal fold on upper edge of tarsus. 



Above olivaceous, with a blackish band from end muzzle to groiti, margined 

 with yellow below, from below eye to axilla. Pale yellow below, sides black- 

 ish spotted. Femora behind black, yellow veined. Limbs paler, rather close- 

 ly cross-barred.
