20 PAHASMILIA. 



it is never broken as in Parn^uillid L/piKini. Ont of twenty-lonr 

 specimens obtained, nine show this mode of multiplying. 



Height 15 to 20 mm., diameter 12 mm. 



Found only in one locality, oiT French Reef, in 45 fathoms. 



PdrasiNilid iiiildiis Duch. & Mich, is perhaps iiearl_v related to this 

 species, l)ut the description and figure are too vague for identifi- 

 cation. 



PARASMILIA M.-Edw. & H. 



Farasmilia Lymani Polkt. 



Plate M., figs. 8, 9, 10. 



Corallum more or less (dongated, conical, nearly always attached 

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

 small, fhiely granidated. subeqnal or alternately larger and smaller, 

 e(iually developed fiom base to to]). (Jalicle circular or slightly 

 elongated or ii'regnlar. Fossa moderately deep. Five cycles of 

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

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

 rather large and Hat granules joined sometimes in oblique ridges. 

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

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

 paliform lobes are formed b\' the peuidtimate sejita : whilst the 

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

 except the last. Dissepiments rudimentary. niend)ranii'oi'm, nearly 

 horizontal, only two or three in nund)er in an interseptal chand)er. 

 They are too faintlj- represented in fig. 10. 



The propagation is by buds on the se])ta in the interior of the 

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

 of the young ; the latter canving a fragment attadied to the base 

 generally through life. 



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

 nun. in the greatest and \'-\ in the smaller diameter.
