The Development of the Ovary of Culex.—By V. Natu. 
When the female culex emerges out of the pupaits ovary has sivonee 
reached an advanced stage of development. The ground tissue is ma 
up of cells ~ fibres mixed witha sack large number of tracheae. The 
vary is bounded by a limiting membrane and has also alumen. A large 
jicanbine of sais lie in tubes which Fines i the follicles grow 
ndary of a follicle is syncitial. This aynsinen! may 
be called the follicle layer. The content cells of the follicles are all simi- 
lar in young ovaries. Each has got a prominent nucleus with a single 
compact karyosome 
Unless the sainmauitces are fed on blood, development stops at this 
stage. If fed on blood development proceeds rapidly in the following 
way :— 
One 
single compas karyosome, e fut ovu uclei of 
other content cells become mu i mies sed their armeicaee heel up 
into a large number of chromatin grains. These are the nurse cells des

content cells unite and there is now a single sheet of protoplasm contam-

nurse cells and their nuclei lose their individual identity and add to the 
cytoplasm of the ovum. Prominent ro grains of 1 ow appear in
