The Whistostylos arc slioi't, ;;iMi(-i;illy erect, ;ilt Ihhi<,'1i some tend to 

 cli-oop through the row of tent;icles, and tliey are closely set witli 

 inalegouophoies, cliaracterised by their elHptical shape, and l)y the 

 replacement of tentacmlar rudiments by a single terminal wart. 

 Unfoitunately, female gonophores have not been observed. The 

 characters, however, ])oint to identity with T. crocea, the male 

 gono[)hor»'s of which, according to Allman, are "destitute of 

 [tenlaculiformj processes," although Toriey's oi)sei'vations show 

 that the presence or absence of tentacular proce.sses is variable*.

T. crocea has been found on the Atlantic (Agassiz) and Pacific 

 ('i\>rrey) coasLs of North America, and in Plymouth llaiI>onr on a 

 ship from Pei'u (Jirowne). 8{)ecimens were obtained growing 

 .-imougst barnacles on the screw-casing of the German Antarctic 

 Expedition ship ' Uauss,' while it was in the (South Atlantic, and 

 \'anli(il1en is of opinion that the specimens settled on the ship 

 during its pa.ssage through the south of the Indian Oceant, 

 in which, until the present record, the species had not been

A few hydrotheca^, referred to this species, were growing upon

 The liydranths bear twenty f.tMitacles. Without the presence of 

 the gonaugia the idt'ntification of tiiis species is luicertain, owing 

 to the re.seud)lance of the tro[)hosome to that of Cli/lid jolmstuni,
