the covering membrane, which belongs to the kenozooecium, is fnrnished with 

 numerous, pointed, scattered chitinous denticles, which thus corresjjond with those, 

 found on the other zoa>cia. The distal wall between the ooecium-hearing zooe- 

 cium and the kenozooecium is, as in F. unciiuita, much bent at an angle and 

 I'urnished with a thickened margin. The kenozooecium has no operculum as it 

 has been figured by Busk. 



The colony has a similar structure as in the foregoing species, but the zooe- 

 cia are arranged in 6 longitudinal rows. A colony from Port Phillip Heads, Victoria 

 (Miss Jelly). 



According to information kindly sent me by Mr. K. Kirk])atrick I must also 

 refer F. atlaiilica Busk' to this genus.

The zod'cUi without spinous processes; the distal wall has at its inner corner a 

 single rosette-plate; the ooecla are in almost their whole extent immersed into 

 the proximal i)arl of the ordinary zoa'cium, and project only very little on the 

 surface of this; the avicularia are attached by a wide base or partially immer- 

 sed, with calcareous transverse bar; the colony jointed.

The zocecia wide, rounded rhombic, with a memlManous frontal area which 

 occupies almost the three-fourths of their length, and which, except for the pro- 

 jecting distal edge, is furnished with an immersed cryplocyst in the remaining 

 marginal part. Each distal wall is furnished with one, and the distal half of each 

 lateral wall with a single uniporous rosette-plate. 



The avicularia which occur in pairs for each zooecium are elongated, some- 

 what curved, tapering towards the proximal end and furnished with an arched 

 outer surface. They are placed in such a way that with their inner lateral edge 

 they border on the distal half of a lower zooecium and with their outer lateral 

 edge on the proximal half of a higher zorecium in a neighboining row. At the 

 distal end there is an elongated frontal area perpendicular to the longitudinal 

 axis of the avicularian chamber. The triangular mandible, which is directed obli- 

 quely outwards and proximally and which is furnished with a Uuida, has like
