which is darker close to the lines than elsewhere. In the two 

 largest examples another light stripe, yellow in the largest one, 

 white in the other, extencls along the upper and inner side of 

 the tibia. In one of the small specimens there are no stripes 

 at all, and it is possible that the non-striped form, described by 

 MocQUARD from Isaka in the southwest of Madagascar, also 

 lives in this district. ^Ir. Kaudern says, however, that all 

 the large specimens he saw had distinct yellow stripes, and 

 probably this example has only retained its early colour longer 

 than the others; in fact, the stripes are rather indistinct also in 

 the other small specimens; first in the fullgrown stage they 

 seem to be perfectly distinct. Possibly, the two forms may be 

 regarded as geographical varieties. 



The animals live among tall grass (as high as 2 m.), to the 

 coarse stems of which they usually were found clinging. They 

 are then very like their surroundings and are very difficult to 

 see; in this position they remain absolutely still and do not move 

 before they can nearly be caught by the hands.

One specimen, 40 km from Sainte Marie de Marovao}', 

 22/9 1906, in a clay-pit in the plain. 



The colour in spirit is olive brown above, with the sides 

 considerably lighter and the under surfaces, except the chin, 

 white. Two bands of the same colour as the back extend from 

 the e3^e, the one to the shoulder, the other to the angle of the 

 mouth. According to what Dr. Kaudern says, the specimen, 

 when alive, was light red with a tint of blue. The specimen 

 agrees ver}^ well with Boulenger's description, with the ex- 

 ception of the tympanum which is completely hidden, and of 

 the belly which is distinctly tuberculated (not smooth). 



Calophryiius calcaratus Mocquard.

 Two specimens, 18 and 22 mm in total length; Andranolava 

 in a moist place near the river.
