 tissue separating the actual testes from the water vascular spaces. 

 The testes, however, do project with their covering into the spaces 

 (see text-fig. 25, p. 202) here and there, and there is thus a very 

 close anatomical relation between them.

In longitudinal horizontal sections (text-fig. 25) it is obvious 

 that the testes of Otiditcenia form a layer which is, as a rule, only 

 one thick, though here and there two testes lie one in front of the 

 other. The distinction between the interstitial tissue separating
