Hierbei p. 736 eine Erörterung über Maeotias inexpectata Ostrooumoff

 eight groups (four perradial and four interradial) and a few small isolated 

 tentacles between the groups. G. corynetes (Gosse). 



Olindias F. Müller 1861 : Petasidae with numerous tentacles, of which there 

 are two distinct kinds. A series (primary) of short stiff tentacles, which are 

 carried outwarts and have their bases attached to the ex-umbrella; and a 

 series (secondary) of long flexible tentacles, which hang downwards from the 

 margin of the umbrella. No adhesive disks on any of the tentacles (Browne

Gonionemoides Mayer 1900. Petasidae with numerous tentacles, of which 

 there are two distinct kinds. A series (primary) with adhesive disks and 

 another series (secondary) without adhesive disks and with more numerous 

 and larger bands of nematocysts (Bro\vne 1904 p. 735). G. geophila Mayer 1900.

 or all of the tentacles. With four or six radial canals, and with or without 

 blindly-ending centripetal canals. With gonads upon the radialcanals. 

 1. Gonionemus. Mayer (3) p. 19: With an adhesive disk near the distal ex- 

 tremity of each and all of the tentacles. Tentacles all similar each to each 

 and projecting in a zone from the sides of the bell, above the margin, their 

 entodermal cores traversing the gelatinous substance of the bell. Four 

 gonads, ribbon-hke and deflected alternately to one side and the other 

 of the radial canals. No bhndly-ending centripetal canals. Numerous 

 otocysts upon the bell-margin. — Hierher: Gon. depressum n. sp. Goto 1903
