976 NOTES ON A BEROID OF PORT JACKSON. 



sensitive pole. Single groups of the spindle-shajoed pigment cells 

 are found also in other parts of the body, so on the paddle-ribs 

 and the mouth margin. 



As a])pears from this description of the colour my specimens are 

 not exactly similar to those of Lesson (9, pi. XVI., fig. 2.) I 

 should however, not consider this as of any importance, as the 

 colouring of the plates in the Coquille Atlas is not very accurate. 



I am at present so loaded with other work that I have not the 

 leisure to examine all the organs of Neis in the same minute 

 manner, and I have therefore directed my attention to those which 

 seemed to me most interesting. 



I have again endeavoured to prove a connection between the 

 Sub-epithel nervous plexus with those Mesodermal threads which 

 Eimer (5) has declared to be nerves, and to which also Richard 

 Hertwig (6) is inclined to ascribe a nervous function. It is true 

 I do not agree with Chun (3), who denies that these Mesodermal 

 fibres are nervous, but I must confess that my endeavours to 

 find this connection in Neis have been as fruitless as in Cyanea.
