lOß s. nom 



of tlio ovnry, is of nn irrou'iilnr sh.'q^e, nnd ocrii])ies :i jiosition 

 anterior to the rest of the ovary (Pi. XV, fiii'. 1, or). The 

 reinnining part is twiee bent on itself at equal distances apart so 

 tliat it rna,v be considered as covisisting" of four ])ortions united end to 

 end. The ovidut ]iortion is very much laru'er than the other three 

 portions. 



In Jlcxacoliile the ovary makes numerous, exceedinü'ly complex 

 Avinding's ^vhicli can not be described with any degree of clearness, and 

 the ]-eader is therefore ref(:'rred to figs. 1 & 7 of V\. XIV. In llexaco- 

 ti/lc acuta I ha\e not been able to obtain a general view of the whole 

 ovarv, and û<j;. 1 on the ])late just referred to has l)een c<^mposed from 

 a series of sections, controlled as nuich as was practicable by examina- 

 tions of the specimens mounted /// tola. The general form of the 

 ovary is that of a long cylinder bent <:)n itself at its middle portion, 

 each half of which ])iakes numerous coii volutions. 



In Ej){hd('Jl(( the ovarv is a simple, spherical body, in which 

 the zones of formation and growth can not l)e distinctly se])arated 

 from e:ich other, but the vounger ova are found towards the 

 periphery, while the riper ones are situated in the central part. \n 

 some species of 'J'risiomiim also the (nai-y is simply an irregidarly 

 gloljtdar l)ody ; but in most species it consists of a certain nundxa- (^f 

 more or less distinct lobes, which are incompletelv separated fi'om one 

 another by an intervening laver of connecti\e tissue, all however freely 

 communicating with one another at the centre of the ovary. As in 

 Epihcldla the unripe ova occupy the ]x^riphery, while the rijier ones are 

 situated more in the central part. 



The ovarian ova are in all the species totally destitute of any 

 external membrane.
