« It lias beeii so confused with otliers, that it is uiisafe to give 

 every assignée! habitat for this species, which however appears 

 to be common and generally distributed on the British coast. »

«Hab. — In deep water parasitical in tufts of T. indivisa and 

 Eudendr'mm rameiim. » 



« This species grows in complicated tufts. The tubes are about 

 3 inches in height. slender of a pale colour, thin und corneous, 

 smooth and unwrinkled. except after being dried, when sorae 

 parts appear to be shightly wrinkled, particularly at the ori- 

 giii of the branches. The naked body of the polype is rose red, 

 more or less deeply tinted, while the tentacula are milk white or 

 faintly tinged with red. The oral séries is very short and usually 

 held in an erect position. The other forms a circle round the 

 most bulging part of the body and consists of more than twenty 



long filaments, which spread like rays from a centre the 



reproductive bulbules, which puUulate from the inner side of 

 the bases of the inferior tentacula. When few in number and 

 immature, the bulbules are sessile and separate, but in their 

 progress to évolution they form grape like clusters, each se- 

 parate bulbule is of a roundish or oval shape, consisting of a 

 white albuminous coat with a dark red centre. » 



VAN Benedex has referred the Tahidaria to the T. cala- 

 maris of PALLASfrom which the size alone is sufticient to prove, 

 that it is distinct. I hâve felt rather uncertain whether to refer 

 our species to vax Beneden 's. T. calamaris or to the I. coro-
