and Protophormia. The ovaries of Calliphora consist of up to 300 
ovarioles each; of Cynomyopsis, about 60; of Cynomya, 50 to 75; 
of Cyanus, 75 to 100; and of Lucilia and Phaenicia, about 100. 
The ovarian ducts typically commence as funnel-shaped ex- 
tensions of the ovarian capsule and unite on a median line to 
form a common oviduct. In Phormia these are somewhat elong-

ate; in Rhyncomyia they are short. In Lucilia they are nearly 
one-half as long as the common oviduct. 
The common oviduct is extremely extensile, averaging about 
2 mm. in length in the retracted ovipositor of Calliphora vicina, 
or considerably more than that length when the ovipositor is ex- 
tended. This passes posteriorly just ventral to the rectum as far 
as the posterior portion of the rectal pouch, where it bends 
abruptly to pass into a ‘‘preuterus,’’ then into the uterovaginal
