Patera Less. I refer this genus, with doubt, to the family of Cya- 

 neidas, no mention being made by Lesson of the genital 

 pouches. The arrangement of the tentacles, though there are 

 twice as many, is similar to that of Stenoptycha; but the 

 oral appendages form a convolute mass of meandering folds, 

 the main branches of which terminate in a pinnate lobe. 

 P. cerebriformis Less. — Dianoea cerebriformis Less. (Zoologie de la 

 Coquille, Zoophytes, PI. 10). — Atlantic Ocean, wider the equator, 

 Long. 25° W. (Lesson). 



Donacostoma Agass. From the centre of the actinostome projects 

 a fleshy proboscis, at the extremity of which are a number 

 of slender tentacles. Like Patera, it has sixteen bunches of 

 tentacles, arranged in a single row in each lobe. The genital 

 pouches are very wide, and conceal the whole actinostome, 

 with the exception of its central i^eduncle, which hangs below 

 them. Lobes of the margin of the disk angular, so that the 

 margin itself appears straight, and is only cleft at intervals. 



D. Woodii Ag. Disk purplish, with white margin ; upper surface 



papillous. Tentacles of the same color as the disk; genital 

 pouches paler. — China Sea, off Tido Timoan (W. W. Wood).
