1. Pelomedusa galeata, Schoepff. 



A single young specimen (Mount Kuldush, 18.12.94). On the 

 left side, the pectoral shield reaches the median line, whilst on the 

 right the humeral and abdominal shields are narrowly in contact. 

 The specimen is therefore intermediate between the typical form 

 and P. gehajke, Eiipp.

This species is closely allied toH. Jiomceolejns, Blanf ., from Socotra
