Flabellum rubrum (Quoy & Gaimard 1833) Bourne 1905. 



Turbinolia rubra Quoy & Gaimard 1833, Voy. de PAstroIabe, Zoophytes, p. 188, plate XIV, figs. 5 — 9. 



Flabellum aculeatum Edwards & II ume 1848 (10), p. 272, plato VIII, figs. 3, 3 a. 



Flabellum debile E. & H. (10), p. 270, plate VIII, fig. 2. 



Flabellum owenii E. & H. (10), p. 279, plate VIII, fig. 9. 



Flabellum spinosum E. & H. (10), p. 271, plate VIII, fig. 4. 



Flabellum stohesii E. & H. (10). p. 278, plate VIII, lig. 12. 



Flabellum sumatrense E. & H. (10), p. 271. 



Flabellum variabile Semper 1872 (26), p. 245, plates XVII, XVIII, figs. 1—10. 



In 1872 »Semper (26) with good reason comprehended the six above-mentioned 

 species of Edwards & Haime in a collective name, F. variabile. Moseley in 1880 (24, 

 p. 172) retains one of the original names, viz. F. stokesi E. & Ii., instead of Sempi;r"s 

 F. variabile. Gardiner (11) identifies several species with F. rubrum (Q. & G.) (1. c., 

 p. 125) and presumes that F. slokesi Moseley (= F. variabile Semper) niay be placed 

 as a synonym of F. rubrum (Q. & G.) (1. c, p. 130 — 131). Bourne (4) is certainly con- 

 vinced of the identity of F. stokesi Moseley (— F. variabile Semper) with F. rubrum 

 (Q. &. G.), but he thinks that the latter name does not inelude all the other species, 

 which were placed as synonyms by G \rdiner. In default of sufficient materials for 

 examination, I can neither ref ute nor adopt Gardiner's opinion, and I join that of 

 Bourne, which seems to me to be fully correct. 



In Dr. Mjöberg's collection there are five specimens, all from the Pearl-Banks 

 off Cape Jaubert: 1. 42 miles W.S.W., 15.7.11, 72 feet; 2. 48 miles W.S.W., 15.7.11, 78 

 feet; 3. 45 miles W.S.W., 17.7.11, 72 feet; 4. 48 miles W.S.W., 15.7.11, 78 feet; 5. 42 

 miles W.S.W., 11.7.11, 36 feet.
