larger scale is included herein ; this 

 will the better enable one to per- 

 ceive the difference in aspect be- 

 tween the typical form of the species 

 and that described hereunder which 

 for the present I regard as a 

 variety. 



EchinochaJina reticulata var. (PI. 

 xxxi., fig. i). 



This variety, represented in the 

 collection by five specimens of 

 \arious irregularly massive form 

 and comparatively large size — the 

 largest specimen measuring 150 

 mm. in height, 230 mm. in length, 

 and 180 mm. in breadth — is of 

 much more compact structure than 

 the tvpical variety, and has spicules 

 of smaller size ; the lamellae, also, 

 appear to be much less regularly 

 interwoven than in the latter. 



The meshes enclosed by the 

 reticulating lamellae average 4 mm. 

 in width, which is only about one- 

 half that of the meshes of the 

 typical variety. The principal styli
