CHELO´NIDES LACUS (αἱ Χελωνίδες κίμναι), a series of lakes (apparently three), formed by the river Geir in Lybia Interior, the middle one being placed by Ptolemy in 49° long., and 20° N. lat. They seem to correspond to the three lakes of Bushashim, Mahalu or Hadiba, and Fittre, the last and largest of which lies E. of Lake Tchad, and the other two in a line to the NE. of Fittre. (Ptol. 4.6.13; comp. GEIR and LIBYA)
