114 COLLINS AND HERVEY. 



neither of us has found it. In Kemp's list mention is made of Chylo- 

 cladia rosea. No specimen with that name is to be found in his 

 herbarium ; the species is northern in its range, and not likely to occur 

 here; some forms of Chrysymenia Agardhii have habitual resemblance 

 to Chylodadia, and may have been the basis for this record.

 p. 714. Rein; Kemp; Moseley; Faxon; Walsingham, Jan., March, 

 Hervey, April, Collins. Appears to grow chiefly in sheltered places 

 among rocks, and may be more common than would appear from the 

 single locality in which we have found it. 



5. C. PYRIFORMIS Borgesen, 1910, p. 187, figs. 8-9. A single, 

 well-developed plant, on the perpendicular wall of a "chasm" near 

 Tucker's Town, below low water mark, April, Collins.

 Attached to Corallines, Ducking Stool, Jan., Farlow; floating off 

 Cooper's Island, Feb., Farlow; Miss Wilkinson; Shore of Gibbet 

 Island, Jan., Feb., North Shore, March, washed ashore, Buildings 

 Bay, Feb., Hervey; dredged in 18 m., Nov., Collins. This species 

 was founded on a single specimen collected at the Canaries, 1882; 

 a single specimen with the ms. name Chrysymenia Lomentaria Crouan 

 is in the Thuret herbarium at Paris; it was dredged once, in about 

 30 meters, in March, in the Danish West Indies; these are the 

 only records outside of Bermuda. In January and February small 

 plants are found among the roots of Saryassum, seldom over 1 cm. 

 high; the larger plants are found washed ashore, probably from 

 deep water. These plants were packed together in crisp masses, 

 with rounded surfaces, like the masses of Valonia macrophysa, but 

 on a smaller scale. No fruit was found on the specimens of our col- 

 lecting, but there were cystocarps on those collected by Farlow in 

 February, tetraspores on those collected by Borgesen in March; both 

 are figured by Borgesen.
