22 ON A NEW FROG FROM ASIA MINOR. [Jan. 20, 



Triangularis 5^er«?.— Extends from upper border of third piece 

 of sternum to lower border of ensiform appendix, and is inserted into 

 second to fifth ribs and upper border of sixth. 



Coccygeus. — Arises from spine of ischium and surrounding portion 

 of bone by tendinous fibres. It spreads out in a fan-like manner, 

 and is inserted into transverse processes of 1-6 caudal vertebrae and 

 into fascia behind this. 



Agitator caurlce. — Arises from posterior margin of outer surface of 

 iliac crest, and from fascia overlying elevator caudae, which attaches 

 it to the last few sacral vertebrae. It is attached to transverse 

 processes of first ten caudal vertebrae. 



Extensor cuudce. — A thick fleshy mass arising as far forwards as 

 first lumbar vertebra. It divides into numerous fleshy bellies which 

 overlie one another, and whose tendons pass to caudal vertebrae at a 

 very variable distance. 



Depressor caudai. — A thick fleshy mass arising from front of 

 sacrum and brim of pelvis, and from tendon of psoas parvus by a 

 few fibres. 



3. Description of a new Species of Frog from Asia Minor. 

 By G. A. BouLENGER, F.Z.S. 



[Received November 21, 1884.] 



(Plate III.) 



A new species of Rana, belonging to the section Ranee temporarice, 

 was discovered at Brusa by Baron von Maltzan, and a male specimen 

 obtained for the Natural-History Museum through Dr. Aug. Miiller 

 of Frankfort. Its nearest ally is Rana temporaria (R. fusca terrestris 

 of Rosel), from which it differs in the longer hind limbs, which equal 

 those of R. agilis, the narrower interorbital space, the longer inner 

 metatarsal tubercle, and also in a few points of minor importance. 

 This Frog .1 propose to name 



Rana macrocnemis, sp. n. (Plate III.) 



Head broader than long ; snout short, obtuse; loreal region not very 

 oblique ; nostril equally distant from the eye and the end of the snout ; 

 jnterorhital space flat, half the width of the upper eyelid ; tympanum 

 two thirds the diameter of the eye ; the distance separating the eye 

 from the tympanum equals nearly half the diameter of the latter. 

 First finger longer than second, with strong swelling ( c? ) showing no 

 trace of transverse division. Hind hmb very long, the tibio-tarsal 

 articulation reaching beyond the tip of the snout ; tibia as long as the 

 fore limb ; toes three fourths webbed, with extremely small sub- 

 articular tubercles ; inner metatarsal tubercle obtuse, elliptical, a
