One of the most characteristic features of the specimen is 

 the great preponderance of triple-star spicules (Plate V. D) 

 0.07 mm. in length, but there are also many spicules of the 

 shapes known as double stars, warted spindles, etc. There 

 are very few spicules of the club-shape which are so character- 

 istic of the species J. juncea and J. gemmacea (Kolliker). 



The colour of the specimens is deep red. 



They were dredged at Rij Bank on November ist at a 

 depth of 25 fathoms. For further particulars of this locality 

 see Alcyonium pachyclados, p. 72. 



The larger specimen is a female containing a few ova, 

 which are oval in shape, with a maximum diameter of no less 

 than I mm., i.e., twice as large as the ova of Alcyonium digi- 

 tatum. Judging from the condition of the nucleus I believe 

 the ova are ready to be spawned 



FAM. : PLEXAURIDAE. 



EUNICELLA PAPILLOSA. (ESP.) PlATE V. C. 



A single complete specimen of this species was sent to me. 

 It can be easily recognised by the very characteristic torch- 

 like spicules .08 mm. in length (Plate V. C.) which crowd the 

 superficial covering of the coenenchym. The coenenchym 

 is partly covered by a thin layer of the same sponge which 

 encrusts Spongioderma. I can find no sexual organs in the 

 specimen which was dredged at Rij Bank in 25 fathoms of 

 water. (See Alcyonium pachyclados, p. 72.) 



FAM. : PRIMNOIDAE. 



Primnoisis capensis (Studer). Plate VI. AA'. 



This species was described by Studer under the name 

 Isidella capensis, but was afterwards transferred to the genus 

 Primnoisis (19). Studer's specimens were obtained in 50 

 fathoms, in lat. 33° 50' S., and long. 17° 52' E.
