From observations traced upon the genital apparatus of the female there exists an ovarian 

 sheath or sack, which, during the early period of pregnancy, is an elongated and subcyliudrical 

 tulif, containing the ovaries proper, two in number, each of which consisting of two, three, or 

 more vascular membranes, attached by their upper edge to the upi)er floor or roof of the sheath, 

 forming either one, two, or more pouches (accoi-ding to the number of those membranes) of 

 the same length as the sheath itself, widely open beneath, though not in a direct communica- 

 tion with one another, since the membranes hang loosely down, resting on the lower tioor of 

 the sheath. 



The eggs are formed within the texture of the ovarian membranes themselves. We have 

 examined the ovaries oi Ennichthys iff crwa/im, when the sheath, withiu which they were con- 

 tained, was not larger than an ordinary quill. Numerous eggs could bo observed in a very 

 immature state, appearing to the naked eye like minute dots. Under the microscope, they 

 exhibited evident traces of the germinal vesicle, surrounded as yet with a very scanty supply 

 of vittilino substance. 



The slieath and the ovaries gradually increase in bulk, as the eggs themselves first increase 

 in size and the embryos afterwards. Tlio sheath is a muscular membrane chielly, whilst 

 the ovarian membranes, we have stated, are altogetlier vascular.
