Family BIMERID^. 



Genus BIMERIA. 



Bimeria BREVis uew species. 



(Fig. 2). 



Trophosome. — Stem simple, growing from a creeping hydrorhiza; in many cases 

 it forms a long pedicel for a single liydranth but in others it may give off several 

 hydranths, each on a pedicel of its own, and occasionally these pedicels may be 

 branched. The greatest length observed was 8 mm. In the branched specimens, the 

 branches do not come off at regular intervals, either vertically or laterally ; each makes 

 quite an acute angle with the stem. The perisarc is quite thick and wrinkled but no 

 definite annuli are formed; the portion around the body of the hydranth is closely 

 wrinkled or creased; hydranth small with 11-12 tentacles. 



Gonosome. — Absent. 



Distribution. — On Tubularia crocea from Katy cove. 



The habitus of this species is much similar to that of Bimeria humilis AUman^ 

 but the stem is relatively much stouter, the hydranths are much smaller and the peris- 

 arc is much more wrinkled. In any case one should scarcely expect to find a species 

 that was obtained in the warm, shallow water of the Tortugas to occur in the cold 

 water of the bay of Fundy. It bears less resemblance to Bimeria vestita Wright as it 

 is a shorter but coarser species.
