PARAGORGIA REGALIS, new species. 

 Plate 15, figs. 1, la; plate 21, fig. 7. 



Two large specimens of this superb species were secured, but they 

 are so friable that it is impossible to remove them mthout much 

 breakage from the narrow-necked jar in which they were preserved. 

 The largest specimen is about 30 cm. in height, rudely flabellate in 

 form. The main stem is round and about 1.2 cm. in diameter. 

 The axis is composed mainly of closely packed spindles and is trav- 

 ersed by numerous water-vascular canals. 



There are two lateral stubs of branches on the lower part of the 

 main stem. Above these the stem forks, and at the base of one of 

 the resultant branches a small furcate branch is given off. Each of 

 the main branches gives off several small laterals, and these again 

 fork, and this mode of branching continues until the ultimate branches 

 are produced. All of the branches and twigs are round, nodulated 

 in places and terminate in rounded knobs. A typical end knob is 

 5.5 mm. in diameter, while the twig supporting it is but 2 mm. 

 across. Branchings up to the eighth order are produced. 



The calyces are inserted on three sides of the branches, nodules 

 and terminal swellings, being more thickly implanted on the distal 

 parts of the colony, lacking on stem and larger branches and seldom 

 seen on the backs of the branches except on the terminal swellings. 



The individual calyces are almost entirely included, being indicated 

 merely by slight swellings around their openings. The margins are 

 divided into 8 distinct lobes. Young polyps are scattered among 

 the larger ones and are of all sizes up to the maximum. The largest 

 verrucse are about 2 mm. in diameter, and some of the smallest 

 are hard to discriminate from zooids. The calyx walls are packed 

 with small terete spindles, as is the general surface of the coenen- 

 chyma. The polyps are completely retractile. The upper parts of the 

 polyp bodies are armed with 8 longitudinal bands of small red 

 spindles, very short and stout and longitudinally arranged. These 

 bands broaden at the tentacle bases and pass on up the dorsal sur- 

 faces of the tentacles, where they are usually transversely placed, 

 but may lie in any direction. 



The smaller or rudimentary polyps so intergrade with zooids, if 

 the latter are present, that it is hard to determine which is which. 

 Possibly the zooids are lacking altogether.
