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, Mahaluor 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)
