Panama, — F. H. Bradley. 



The following description, which is unaccompanied by numbered 

 specimens, probably refers to this species. " Body large, 1-5 inches in 

 diameter; the column fluted, with 48 vertical sulcations, correspond- 

 ing to lobes of the base and disk. Base 2 inches in diameter. Disk 

 broad, with wrinkled flutings corresponding with the tentacles ; mouth 

 small. Tentacles 48, in two series of 24 each, slender, Vh inches long. 

 Color of column red ; tentacles olive-brown, with a light streak up 

 the inner side ; mouth surrounded by 24 rays of alternating greenish 

 and reddish brown, running to the tentacles. Grows to a large size. 

 Specimens were seen 3 inches across the disk, others were reported as 

 large as 5 inches."

Epiactis Verrill, gen. nov. 



Integument firm. Column subcylindrical, capable of involving the 

 summit and contracting into a hemispherical form, with a distinct sub- 

 marginal fold or " parapet," separated from the tentacles by a narrow 

 fosse ; surface smoothish, in contraction reticulately wrinkled. Kear 

 the base it is surrounded by a circular wrinkle or depression, upon 

 which there are borne a variable number of young, of various sizes, 

 appearing as if originating from surface buds, but possibly produced 

 from ova attached in this place to the skin. These young may be re- 

 moved without rupture of the integument, although they adhere quite 

 firmly and leave a depression in the surface of the skin, but there are 

 no apparent lateral openings in the wall. Tentacles numerous, about 

 50, in preserved specimens short and thick, arranged in several rows. 



Epiactis prolifera Ven-m, sp. nov. 



Base dilated, crenulate. Column in contraction hemispherical or 

 subconical, broader than high ; surface with fine reticulated wrinkles 

 above, near the base transversely wrinkled, the uppermost of these 

 wrinkles more marked and bearing, in all except very small specimens, 

 a circle of young of various sizes, which vary in number from very 

 few up to 30 or 40. When most numerous they are closely crowded, 

 somewhat in two rows. Parapet well marked, its edge rises into 

 sliglit ridges between vertical wrinkles. Tentacles in alcoholic speci- 

 mens short, stout, obtusely rounded at the end, about 50 in number 

 in the larger specimens, and apparently arranged in several rows and
