23. Microhyla rubra.— This little frog is fairly common in the low 

 country, but not easy to find, as it is strictly nocturnal. The breeding 

 season lasts from June to November. The eggs are found floating in 

 flat transparent masses ; each egg is hexagonal and has a diameter of 

 5 mm. 



Tadpoles. — Length of the body about one and a half times its breadth, 

 less than half the length of the tail. Nostrils placed close together on 

 the upper surface of the head, nearer the eye than the end of the snout. 

 Eyes on the sides of the head, nearer to the end of the snout than to the 

 spiraculum. Distance between the eyes six times that between the nostrils, 

 two and a half times the width of the mouth. Spiraculum on the middle 

 line opening into a transparent sheath of skin directed downwards and 

 backwards close to the anus, which also opens in the middle line in the 

 lower edge of the subcaudal crest. 



Tail. — Length four times its depth, very acutely pointed. Lower 

 crest twice as deep as the upper. Depth of the muscular portion more 

 than half the total depth. 



Mouth. — This has neither horny beak, labial teeth nor papillae. The 

 lower lip is contractile, and as Capt. Flower describes it, is continually 

 expanding and contracting. 



Colour (in life). — Body almost transparent, above reddish pink with 

 very fine dark-brown spots, only visible as such with a lens. These 

 form dark marks over the eyes and nostrils, and they also form a more 

 or less diamond-shaped figure on the back. Both the crests are densely 

 spotted towards the end. Length of body 11. Length of tail 25. 

 Breadth of body 8 mm. Depth of tail 6. Toes at first completely webbed. 



24. Microhyla ornata. — Like the last this frog is nocturnal, and 

 during the day may be founl hidden under leaves or stones. It is 

 fairly common in Trevandrnm, and tadpoles may be found in June and 

 July. They have been described by Capt. Flower. The eggs are laid in 

 flat transparent masses. They are irregularly shaped and considerably 

 smaller than those of Microhyla rubra, having a diameter of 2 mm. 

 only. Toes at first completely webbed. 



25. Callula obscura. — Of the habits of this little frog I can say little 

 except that they are nocturnal. I have not found it on the hills. One 

 specimen I found in the tin pot of a putting hole on the Residency 

 links. I have only lately obtained the tadpoles in the month of July.
