 Vii'gularia elongata, Gabb, Pro^ Calif. Acad. Sci. 1863, ii. p. 167. 



Ilab. California ; San Francisco. 



Larger and stouter than S. gracilis ; pinnae broader and more over- 

 lapping, leaving a naked space between the rows for only a short 

 distance in the middle, twenty occupying an inch ; the spines are 

 also larger and fewer. 



Dr. Herklots refers to the Funiculina cylindrica of Lamarck with 

 doubt. It has only been described from some stony axis. I think 

 there is little doubt of this being the axis of the coral which I 

 described as PrimnoeUa austraJasice, the axis of Avhich well agrees 

 with Lamarck's description. He also inquires what is the Pennatula 

 scirpea of Pallas (Zooph. p. 372. n. 218)? which has not been recog- 

 nized in coUectious. — Crt'ciy, Ann. ^- Mag. Nat. Hist. 1860, v. p. 21. 



The Alcyonoid described and figured by Linne under the name of 

 Pennatula mimhilis (Mus. Adolph. Frid. Reg. t. 19. f. 1) appears to 

 have little analogy with Virgiilaria mirabilis. It has a thin slender 

 stem, attenuated at each end, and with a simple series of very short 

 polypes on each side. Cuvier, in 1817, formed for it the genus 

 Seirpeaire (Reg. Anim. iv. p. 85) ; Lamarck placed it under the 

 genus Funiculaire, by the side of Pavonaire, under the name of 

 F. cijlindrica (H. A. s. V. ii. p. 423, ed. 2. p. 640) ; Fleming thinks 

 it is not distinct from Virgulaire (Hist. Brit. Anim. p. 507) ; and M. 

 de Blainville regards it as only a sjiecies of Gorgonia (see Man. d'Act. 

 p. 515) ; but none of these opinions appear to M. Milne-Edwards to 

 be admissible (see CoraU. i. p. 114). 



Fam. 2. PENNATULID^E or PENNIFERA. 



Coral elongate or broad, pinnate ; base sterile, subclavate. Polypes 

 in expanded, fan-shaped pinules that arise from a narrow base in a 

 series on each side of the front edge of the rachis. Polypes retrac- 

 tile. Axis calcareous, slender. 



Pennatideae, Gray^ Ann. 8c Mag. Nat. Hist. 1860, v. p. 21. 



a. Pinnules elongate, angular. 

 * Back of the rachis granular or tubn-cular, icith undeveloped polypes. 



8. PENNATULA. 

 Coral pen-shaped, oblong. Rachis rough behind, spinulose. Stem 

 short, thick, with a sunken central groove and a scries of spines on
