Specific Character. 



The trunk assuming the form of a small tree, with two main branches. The branches knotty; the knots densely 

 beset with polyps and zooids. Between the knots the branches are naked, smooth, and slender. The polyps retractile, short, 

 and abounding in calcareous corpuscles. 



Gondul mirabilis, n. g. et sp. 



Tab. X. 



Gondul mirabilis does not admit of being referred to any of the families instituted for the Pennatulidæ; and hence 

 we find it necessary to establish, not only a new family, but also a new section, the 4th accordingly of the order Pennatulida. 



Order: Pennatulida. 



Section IV: Gonduleæ, n. sp. 

 The rachis fixed, with developed bilateral pinnules, and furnished with long calcareous spicules. 



Family I: Gondulidæ, n. sp. 



Polypidom without a stalk, fixed, furnished with bilateral pinnules, in which are calcareous spicules, having along 

 its centre a canal, divided by 4 valves into as many longitudinal canals. 



Genus I: Gondul, n. sp. 



Polypidom short, erect, fixed. No stalk. The rachis terminating in a diskoid basal part, by which it is attached 

 to the bottom. Ventral surface naked. Sides and dorsal surface occupied by pinnules, bearing large retractile polyps. No 

 calcareous axis. But very few zooids on the dorsal surface. Throughout the whole of the central part of the polypidom 

 a main canal, divided by 4 fillet-shaped, longitudinal, close-set valves into as many longitudinal canals, of which the two side
