TJie Rotatorian Genus Diaschiza. 139> 



for the genus, tapering ; toes about | length of rest of body, very 

 thin except just at base, very slightly recurved ; oesophagus very 

 long. 



This uncommon species was observed by F.E.D.N. (one example 

 only) on October 10, 1891 ; and a drawing was then made by him, 

 of which fig. 2 is a copy. 



The original description is given by Dr. Barnett Burn in the 

 February number of Science Gossip, 1890. 



From this description very little can be gathered ; but from 

 the drawing which accompanied it, the toes, the long oesophagus, 

 and the trace of dorsal cleft there portrayed give just sufficient 

 detail for identification. 



The remarks upon its resemblance to F. eva and F. cceca, serve 

 to make the identification more a matter of certainty. 



We have every confidence, therefore, in classing this as a 

 Diaschiza, from the general shape of body, foot and toes, and 

 especially from the dorsal and lateral clefts well figured in 

 F.R.D.N.'s original drawing. 



The specific marks of this species are : — (1) the pair of very 

 long thin toes, slightly clubbed at the base, but tapering at once, 

 not at mid-length as in the case of D. eva, although they resemble 

 those of eva in having flexible extremities ; and (2) the extra- 

 ordinarily long oesophagus. 



This rotifer has the habit of throwing its toes over its back., 

 and into some of the other postures characteristic of D. eva. 



The setae on the foot were not looked for. 



The jaws, food, and size were not recorded. 



Eare, not seen since 1891 ; from Mr. Bolton, Birmingham.

We are strongly of opinion that this is not a Diaschiza at all ; 

 but out of respect to Mr. C. F. Eousselet we include it in our list.
