20 PARASMILIA. 



it is never broken as in ParasndUa Lymani. Out of twenty-four 

 specimens obtained, nine show this mode of multiplying. 



Height 15 to 20 mm., diameter 12 mm. 



Found onl}^ in one locality, off French Reef; in 45 fathoms. 



ParasmiUa nutans Duch. & Mich, is perhaps nearly related to this 

 species, but the description and figure are too vague for identifi- 

 cation. 



PARASMILIA M.-Edw. & H. 



Parasmilia Lymani Poukt. 



Plate VI., figs. 8, 9, 10. 



Corallum more or less elongated, conical, nearly always attached 

 to a fragment of the parent, otherwise free. Wall very thin. Costa3 

 small, huely granulated, subequal or alternately larger and smaller, 

 equally developed from base to top. Calicle circular or slightly 

 elongated or irregular. Fossa moderately deep. Five cycles of 

 septa, and six very irregular systems, having often the appearance 

 of a greater number ; the septa entire, moderately exsert, with few 

 rather large and flat granules joined sometimes in oblique ridges. 

 The internal edge of the septa is deeply divided into lobes forming 

 false pali and sometimes a false columella (Plate VI., fig. 10). The 

 paliform loljcs are formed by the penultimate septa ; whilst the 

 twisted ones, simulating a columella, rise from the other cycles, 

 except the last. Dissepiments rudimentary, membraniform, nearly 

 horizontal, only two or three in number in an interseptal chamber. 

 They are too faintly represented in fig. 1 0. 



The propagation is by buds on the septa in the interior of the 

 calicle, in the parent, the walls of which are burst by the growth 

 of the young ; the latter carrying a fragment attached to the base 

 generally through life. 



The largest specimen (incomplete at the base) is 4 cm. high, 18 

 mm. in the greatest and 13 in the smaller diameter.

Off the Samboes, in 96 fathoms. 



Off" Alligator R. ( f, in 110 fathoms. 



Off Conch Reef, in 117 fathoms.
