of the sterile polyps is about 2 millim. The proliferous polyps 

 are very much smaller than the others, being on an average 

 hardly one third of their length ; they further differ in

 stone-shaped sporosacs arise on very short peduncles. The 

 proliferous polyps are very numerous in the specimens 

 obtained in January, very few in those obtained in November, 

 and apparently absent in those obtained in March.

This small Scorpajnoid fish was described and figured in 

 J. A. S. B. vol. Iviii. pt. ii., 1889, p. 299, pi. xxii. fig. 4.
