EMYS SUBTRTJUGA. 



In a young specimen the black bands on the back are 

 much less distinct , whereas each of the sternal plates carries 

 a large dark blotch closer to the posterior than to the an- 

 terior margin, each of these blotches being surrounded by 

 a thin blackish line. 



The Leyden Museum is at present in possession of two 

 specimens of this species , one adult , the carapace of which 

 measures 30.5 cm. over the curve , one young individual 

 of about 12 cm.

With respect to this species considerable confusion has 

 persisted up to the present day, which by the following 

 lines I hope to be able to clear away. 



The three original specimens on which it was founded 

 and which are now before me, were captured in Java by 

 Kuhl & V. Hasselt, most probably in the most western 

 province of Bantam. They reached the Leyden Museum, 

 were examined by Boie, who in his MS. list of the Ma- 

 layan reptiles identified them with Emys trijuga Schweig- 

 ger, from the continent of India. In 1835 Schlegel gave 

 a short description of the specimens in the Fauna Japo- 

 nica (Reptilia, p. 64) in which all the most salient cha- 

 racters : the large head , the yellow bordering of the shell 

 and the curious distribution of colours on the sides of the 

 head are distinctly enumerated. However he fell into 

 Boie's error by bringing the specimens to Schweigger's 

 JÏJ. trijuga. This error was corrected in the: Verhandelin- 

 gen over de Natuurlijke Geschiedenis der Nederlandsche 

 Overzeesche bezittingen, Leiden 1839 — 1844, on p. 30 of 

 the part Reptilia, published by Sal. Muller and himself. 

 Here the name E. suhtrijuga was first given to the three 

 Javan specimens , the large size of the head was again
