The head stained deeply and pre-sented a sUghtly curved spine at one extremity, while surrounding the head wasa clear zone (apparent capsule). From the portion of this capsule correspond-ing to the larger extremity of the head, a delicate, faintly stained tail was seento emerge. This tail was rendered more distinct by the application of heatwhile staining. Measurements of these cells were found to be as follows : Total length, . to mm., or to in.

Spermatic fluid from the cat (Fig. 8) was found difficult to study, as but fewspermatozoa were present. Each spermatozoon presented a tibrillated tail, andat times this fibrillation was seen to surround the head. The head staineddeeply, and at times a centrosome was distinct. Decided irregularity was notedin the size and form of the heads, which partially explains the variations foundin the measurements of these cells. Total length, . to mm., or to in.
