coasts it is the most common frog. In Sikkim I observed it up to 7000 feet, 

 and the specimens obtained at higher elevations are generally young, or 

 perhaps never grow to a large size ; their hind limbs are often proportionately 

 much longer than in adults. 



Since the notes on S,. lymnocharis, var. Nicoharensis, (J. A. S. B., Vol. 

 xxxix, Part II, 1870, p. 144) were published, I had received a large specimen 

 of this frog from Nancouri, Nicobar islands. The length of body is 

 2 "5" ; form and coloration typical ; snout obtuse as in the Andaman variety, 

 but the webbing of the toes is very slight, the web reaching on the 4th toe 

 only to the 2nd joint, the three terminal joints being free ; on the 5th finger 

 the two terminal joints are free. No distinct cutaneous fringe, either on 

 the inner or on the outer side of tarsus or toe ; inner metatarsal tubercle 

 elongated, marginal, outer nearly obsolete. 



Dr. Anderson (Proc. Z. Soc, 1871, p. 200) appears to doubt that the 

 Andaman and Nicobar forms really belong to Vymnocharis ( = gracilis)^ but 

 does not support his scepticism with facts. I am confident that none of 

 the forms which I have described from those islands and from Penang, differ 

 essentially from the continental frog, and that they can only be considered 

 as local varieties of it. 



Professor Peters recently described (Monatsb. Berl. Akad., 1871, p. 646), 

 an allied species from Pegu as It. hrevipalmata, in which the hind- 

 limb is very nearly double the length of the body ; the hinder side of 

 the femora is light rusty brown with dark marblings. I have not seen this 

 form, but would not be in the least sm'prised, if it should turn out to be only 

 a local variety of lymnocJiaris.

 This species is found between about 4000 and 10000 feet in Sikkim. 

 The adult males have the sides of breast, the inner arms and the fingers 

 externally studded with small, black, horny tubercles. Mr. Blanford found 

 it abundant in the interior of Sikkim.

Jerdon says that his Sikkimensis* differs from Liehigii by its more 

 fully webbed feet ; but this statement is to the point, and as Dr. Anderson 

 does not refer to this comparison, I do not think that his lengthy description 

 gives more information than Jerdon's short reference. In Liehigii the toes are 

 also fully webbed, particularly in the young, but the web reaches only as a nar- 

 row fringe to the tip of the fourth toe, while in Sikkimensis it reaches it in a 

 straight line from the adjoining toes. The proportions of the body and color-
