Description. The male cone-sliaped. attenuated at posterior end, but without 

 peduncle and without any coating of gelatinous substance. The coronal disc cone- 

 shaped, coTered with a coating of short cilia encircled by a ring of long cilia but 

 wholly destitute of the long stiff setæ so characteristic of the corona of the Flos- 

 cularia-females. A hypodermal ring of thick, large cells, a large brain; anteriorly 

 inside the ciliary wreath two red eyes. From the brain two antennæ running to a 

 sharply defined dorsal organ, provided with a tuft of cilia; no lateral antennæ have 

 been observed. \o alimentary canal but before the testis a large globular body, 

 perhaps a rudiment thereof, perhaps a large oil-globule. Two lateral canals ending 

 near the opening of the penis, each provided with three vibratile tags; no con- 

 tractile vesicle. A large testis, filled with spermatozoa; hitherto staflF-formed ones 

 have not been observed; ductus seminalis is curved, provided with cilia in its 

 interior, and with two prostata glands laterally. At its apex a bunch of cilia; during 

 copula the canal is turned inside out and presents itself as a dorsal conical projec- 

 tion, provided with a ring of cilia. Ten transversal muscle bands, which in a 

 very high degree are able to constrict the body and alter its form : at all events 

 two pairs of longitudinal muscle bands. Size of the male 45//. Size of the fe- 

 male 750 i-t. 



The male eggs were found in the tubes; for some time the males are in the 

 egg shell; then for a short time they swim round in the tube of the female where 

 upon they leave the tube; during the few hours they live, they do not seem to 

 leave the female colonies, always encircling the coronas and upper part of the tube.

Western (1893, p. 157) states that Hood is the first who has seen the male 

 and later on sent him females with male eggs in the tubes (April). 



"The eggs were laid in batches of three or four, some two or three hours before the 

 young males ermerged from them. . . . After birth the young males, measuring about Viso in., 

 \vere within the tube, and from it I distinctly saw two or three of them bore their way out 

 through the side, leaving in one case a hole with ragged edges. This process took them six 

 or eight hours. . . . There is a sort of head with two red eyespots. This is surrounded by 

 a ciliary" wreath, of which the cilia are very long and active. Below this the body gradualh'
