NOTES ON THE ANATOMY OF THE GENERATIVE 

 ORGANS OF ARIOPHANTA JULIANA, GRAY. 



i;v H. OVERTON, 

 Sutton Culdlicld, Warwick. 



The specimens which have furnished the following account are some that were 

 collected by the late Mr. Oliver Collett at Galle, Ceylon. 



The position of this species in the genus Ariophanfa, I do not, at present, 

 jjropose to discuss : like many other members of the genus far too little is 

 known of its internal structure, in fact there is a striking absence of any 

 thorough and detailed statement of the anatomical characters of this genus. 

 Semper (Reisen Arch. Philip. 1870) has given short descriptions of certain 

 organs in different species, and Lieut -Col. Godwin-Austen has still more 

 briefly referred to the generative organs of various species, but his remarks 

 together with the indistinct nature of the drawings illustrating them, are 

 almost useless for purposes of comparison, indeed, it is difficult to attach any 

 serious value to them whatever.
