r>18 Mr. G. A. Boulenifer on new 



between Et'ulon and tlie coast, in a pool wliicli some women 

 were fisliins; out with scoop-nets. It was kept alive in a 

 large spiiit-drum halt' filled with water; but it unfortunately 

 escaped. 



L\ goliath, the larcrest frog known, exceedinor in size even 

 B. (jupp}/}\ is most nearly related to the West-African 

 i?. crassipes, Peters. 



Arthroleplis Batesii. 



Tongue with a conical median papilla. Head moderate, as 

 long as broad; snout obtusely pointed, as long as the eye, 

 witli distinct canthus and nearly vertical, concave, loreal 

 region; nostril a little nearer the tip of the snout than the 

 eye; interorbital region as broad as or a little broader than 

 the upper eyelid ; tympanum rather indistinct, about half the 

 diameter of the eye. Fingers rather short, first and second 

 equal ; toes with a short but very distinct basal web, ex- 

 tending as a fringe on each side ; tips of fingers and toes 

 dilated into well-developed disks; subarticular tubercles 

 strong ; two small metatarsal tubercles, inner oval, outer 

 round ; a small tubercle on the tarsus, its distance from the 

 inner metatarsal tubercle less than that between the two 

 metatarsal tubercles. Tibio-tarsal articulation reaching 

 between the eye and the tip of the snout, fcjkin smooth, 

 upper eyelids and flanks with small warts; two curved 

 glandular folds on the back, behind the eyes, converging on 

 the .scapular region ; a strong fold from the eye to the 

 shoulder. Bruwn above, sometimes tinged witii crimson, 

 the outer edge of the dorsal glandular folds sometimes 

 blackish ; a liglit cross-bar between the eyes ; an oblique 

 dark brown band, edged with whitish behind, froin the eye 

 over the temple to the front of the arm, where it terminates 

 in a point; loreal region sometimes bright crimson; limbs 

 with oblique dark cross-bands ; a triangular dark brown 

 patch on the anal region ; lower parts yellow, uniform or 

 with small brown blotches on the breast and on the sides of 

 the belly ; a series of brown spots bordering the lower lip. 



From snout to vent 31 mm. 



Two specimens from Efulen and four from Zima. 



Apart from the very slightly webbed toes and the united 

 outer metatarsals, this very distinct species bears a striking 

 resemblance to Fhrynobatrachus plicatuSj Gthr., which 

 inhabits tiie same district.
