At a considerable distance above the level of the sea, and 

 hemmed in on all sides by the Laurentian hills, is a charming 

 little sheet of water, known as Tadousac Lake. Here occurs a

ON HYPONOME SARSI, A RECENT CYSTIDEAN. 



By S. LovEN. 

 (Reprinted from the "Annals and Magazine of Natural History," September, 1869.) 



The general appearance of this very remarkable Echinoderm 

 is that of a small starfish or a Euryalid. It has a disk, convex 

 on the ventral surface, flattened on the dorsal, and five short and 

 broad rays ; each of these is divided into two short dichotomous 

 branches, terminating in four very short rounded lobes. As in 

 the recent genera Antedon and Pentacrinus, a large, conical, 

 proboscis-like funnel rises in one of the interradial spaces of the
