66 THE EOTIFEEA. 



which are thick, decurved at the tips, and of a length equal to one third of tlie whole 

 animal when extended. The pencil-sketch has not many details of organisation. 



The only note which the observer has added is the following : " It has the power 

 of drawing-in the first joint of the foot into the interior of the body ; and has a peculiar 

 manner of separating the pair of curved toes." P.H.G.]

[SP. CH. Slender, long, gibbous ; front furnished with a protrusile lip ; foot long, 

 with two minute furcate, virgate toes. 



Beyond what the mere outline suggests, as conveyed in the figures, I can give little 

 information concerning this species. With much doubt I place it in the present genus ; 

 and that only on the possibility that two obscure spots, dimly seen in the neck, may 

 have been eyes. They may have represented the trophi. In fact my knowledge of this 

 form rests on a single brief observation. I was examining an aquatic moss, which Dr. 

 Collins procured for me in June 1885, when this little creature glided out. I saw in a 

 moment it was new to me, but my attention was already occupied. There were in that 

 live-box, at that instant, three or four Eotifera unknown to me ; as many papers were 

 before me, on which I was labouring to reproduce the portrait of each, feature by feature, 

 as I could catch it. Here was one more. It was a complete cmbarras des richesscs. 

 What could I do ? I hastily threw in the outlines here given, careful to secure correct- 

 ness in what was produced, but deferring minute examination in the hope of seeing it 

 again ; while I pursued the study of those already in hand. The present subject, how- 

 ever, found speedy concealment among the moss, and I could find it no more ; nor has 

 it ever reappeared. The form, particularly in the lateral aspect, recalls the outre shape 

 of Notommata caudata, with its long neck, elevated back, and slender foot ; but the re- 

 semblance is only superficial. Its chief peculiarities are (1) a slender parallel-sided, 

 squarely-truncate proboscis or lip, projecting medially from the front, which is seen in 

 the side view to be somewhat low in position ; it seemed retractile to some extent ; (2) 

 a long, slender, and tapering foot-joint, furnished with a furcate pair of toes, very 

 minute, of equal thickness throughout, obtuse ; like tiny pegs. 



I can find nothing in Ehrenberg with which satisfactorily to identify it. P.H.G.] 



Length. About T ^ inch. Habitat. Sandhurst, Berks (P.H.G.). 



[N.B. In Dr. Collins's Note-book are pencil-sketches of an evidently large animal, 

 which may possibly be the Triophthalmus dorsualis of Ehrenberg. I have carefully 

 copied the sketches (PL xviii. figs. 14, 14a) ; but the details are not sufficient for dia- 

 gnosis ; and there arc no descriptive notes. I have not myself met with anything like it.
