52 THE EOTIFEEA. 



This Floscule greatly resembles F. ornata, but it is (listinnfuislied by its height, ' 

 the length of its foot, and the shortness of its loltes. The fully extended foot is fre- 

 quently thrice as long as the body. The tube is much wider than usual in proportion to 

 the animal's size, and often symmetrical in shape, like that of F. longicaudata. Two 

 eyes are visible in the adult. This species is prolific and has often many eggs in its tube. 

 As many as twelve female eggs have been counted in the same tube ; and eighteen 

 male eggs in another. Found by ^Ir. C. Cubitt in 1871.

SP. CTT. Lobes fire, broad, without kiiohs, separated by distinct depressions; 

 peduncle short ; setae radiating from the smnmits of the lobes, and fringing the tvhole 

 edge of the coronal cup. 



I think that Grenadier {loc. cit.) is right in supposing that Dr. Dobie's F. cani- 

 jmnnlata is really Ehrenberg's F. pii'ohoscidea. Ehrenberg describes the latter as 

 having six lobes, and also a snout-like organ, of cylindrical form, beset with setaj like 

 those on the lobes, and rising from the depths of the coronal cup above its rim. Gren- 

 adier suggests, as Dujardin had done before him, that this snout-like organ is only the 

 dorsal lobe seen before the corona is fully expanded. I have thought it best, however, 

 to retain Dr. Dobie's name, as F. canipanulala has certainly neither a proboscis nor 

 six lobes : I confess, however, that I have little expectation of anyone's ever finding a 

 Floscule with cither the one or the other. 



The setae often appear to be confined to the thickened summits of the lobes, forming 

 simply a tuft on each. They really, however, fringe the whole circumference of the 

 corona, sloping further away from it as they approach the bottoms of the depressions 

 between the lobes, and even at last pointing backwards towards the foot. The vascular 

 system has been described above, p. 47, and is shown PI. II. fig. 8. Only four vibratile 

 tags are given in Dr. Moxon's figure ; but Grenadier has seen a fifth, whose position 

 is shown in PI. II. fig. 4. A nervous ganglion has been seen by Dr. Moxon. It is 

 situated dorsally on the neck (PL II. figs. 3 and 4, gn]. Nerve threads are drawn by 

 Dr. Moxon, as passing fi-om the ganglion to the three antemife. There is one dorsal 

 antenna, half-way up the coronal cup, and one on each side of the cup close to its junc- 

 tion with the body (PL II. fig. 3, a). They are little more than setigerous pimples. 

 When the coronal cup is furled, the dorsal antenna may be seen on the summit of the 

 eoiitracied Floscule's pear-shaped body. The discovery of the male has been mentioned 

 above, p. 49. Its sperm-sac (s) and penis {p) are indistinctly showi in PI. I. fig. 1, c ; 

 but the dead specimen from which I drew the figure was so lately hatched that its 

 cuticle was more than usually opaque. As many as twenty male eggs have been 



' To obtain a correct notion of the completely expanded animal, the foot and case in Tl. I. fig. 0, 

 should be supposed to be continued quite two inches below the bottom edge ot the page on which the 

 figure is drawn. A small, correctly proportioned figure, is given in PI. D, fig. 2.
