52 Smith and Harger — St. George's BanJcs Dredgings. 



interspaces mostly.as wide as the pores ; from the center of the upper 

 side arises an open, slender, flat, acute spinous process, composed of 

 two anastomosing pieces. The plates of the papillae or suckers are 

 narrow, elongated, bent into a bow-shape, the middle expanded and 

 usually pierced by about four pores, two of which are larger ; the 

 ends are also usually dilated and pierced with small pores ; from the 

 middle arises a flat, spinous process, similar to that of the skin-plates, 

 but smaller. 



Length, in alcohol, about 50""" ; greatest diameter, 6 to 9™™ ; 

 length of longest tentacles, 7"5™™. Color of pi-eserved specimens, 

 yellowish brown. 



Localities o and s, 110 and 150 fathoms. Also dredged, in 1873, 

 oflT Casco Bay. 



This species resembles T. raphanus Duben and Koren (Troschel 

 sp.) in form, but the latter has long-stalked tentacles, branching only 

 near the ends, and the plates of the skin are different in form, and in 

 the perforations, and lack the spinous processes which give the species 

 its rough, scabrous surface, 



? Charybdea periphylla Peron and Lesueur. 



Verrill, Report upon the Invertebrate Animals of Vineyard Sound, p. 724, 1874. 



This species, originally described and figured by Peron and Lesueur 

 from mutilated specimens taken under the equator in the Atlantic 

 Ocean, is doubtfully identified b)' Professor Verrill with a specimen 

 obtained by us east of George's Banks. 



The body in the alcoholic specimen is elevated, bell-shaped, rounded 

 above, with a marked constriction toward the border ; transparent, 

 the inner cavity showing through as a large, conical, dark reddish 

 brown spot, with the apex slightly truncated. Border dcejily divided 

 into sixteen long, flat lobes, which are of nearly uniform breadth 

 throughout, and slightly rounded, or sub-truncate, at the end ; the 

 edges and end thin and more or less frilled ; the inner side with two 

 sub-marginal carinae. Eyes inconspicuous, but small bright red 

 specks are scattered over the marginal lobes. The intervals between 

 the lobes are narrow and generally smoothly rounded, without dis- 

 tinct evidence of the existence of tentacles, except that, in one of 

 these intervals, there is a small and short papilliform process, with 

 brown pigment at the base. The ovaries are mostly wanting, but 

 portions are to be seen as slightly convoluted organs in the mar- 

 ginal region, opposite the intervals between the lobes.
