326 VBRRILL, SYNOPSIS OF 



Length in expansion about 2.25 inches ; diameter .62. 



Port Llojcl, Bonin Islands, attached to pebbles beneath 

 the surface, in the lower part of the littoral zone. Dr. 

 Wm. Stimpson. 



When contracted in alcohol the specimens are one inch 

 to 1.25 long, and .40 to .60 in the greatest diameter. 

 The column is the largest in the middle, diminishing 

 below to the base which is a little expanded. At about the 

 upper third the column suddenly becomes smaller, with 

 strong longitudinal sulcations, between which the surface 

 rises up into papilla-like prominences ; the rest of the 

 column is faintly sulcated longitudinally and strongly 

 wrinkled transversely. The whole column, except a very 

 narrow zone close to the upper margin, is covered by a 

 closely adherent, firm, yellowish brown epidermis. No 

 acontia or loop-holes observable. 



This species diifers considerably from the typical 

 Phellim described by Gosse, and might, with some reason 

 be generically separated. Should this be thought desira- 

 ble I would suggest the name Paraphellia. The principal 

 structural peculiarities are the extremely short, knotted, 

 outer tentacles ; the very narrow, submarginal, naked 

 zone ; the firm, inseparable epidermis, and the papillose 

 appearance of the upper part in contraction. The last 

 two characters are also found in P. gausajpata Gosse.
