a species of Huplotes, and a few of a Colwrus. I have since found it repeatedly in sea- 
water from the Tay Estuary. It is active and sprightly in its manners, browsing among 
the floccose ; frequently elongating and contracting its body, and occasionally swimming 
in the open water.—P.H.G.]

This species I at first supposed to be Ehrenberg’s £. Reinhardti, which has not yet 
occurred to British research; but, on mature consideration, there seem important 
differences, which warrant my raising this to specific rank. Reinhardti is stated to be 
yda inch in length, which is not so large as F’. forficula and F’. gibba; whereas this is 
gz inch in length, and so is a very giant among Furcularie. Then the foot in 
Reinhardti is half the length of the body: in Boltoni about one-fourth ; the toes in the 
former are minute, one-fifth to one-sixth the length of the foot: in the latter rather 
long and slender, full half the length of the whole foot and toes. Ehrenberg speaks of 
‘‘the great eye’’ as an attractive feature in his species; but in this, the eye is, as usual, 
minute and inconspicuous. Lastly, his species is marine, living parasitically on the 
branching stems of the well-known polype, Laomedia geniculata ; whereas mine oc- 
curred in a pool in the heart of England. Thus I venture to pronounce it new; and 
honour it with the name of that energetic microscopist, Mr. Thomas Bolton, who sent it to 
me. It has evidently very close relation with F’. Reinhardti, as is shown by the general 
form, and especially the spindle-shaped trunk, and abruptly tapered foot. It is a true 
Furcularia, as to its trophi, of which I had a very favourable observation ; the mallet 
being slight and feeble, while the incws is strongly developed with wide, glassy, arched 
rami, produced into long decuryed points. 
The front, in life, is probably conical, as usual; but in the condition in which alone 
I have seen the species, the cone was so low that its outline was nearly straight, with a 
minute but clear red eye-speck occupying the very centre of its edge. The mastax is of 
the usual large dimensions, followed by a slender esophagus, an ample stomach with 
small oval glands, a separate intestine full of dark granulate food, an ovary with a great 
opaque maturing egg, and what I took for a contractile vesicle. The trunk is thickest 
at the lumbar region, and that whether viewed laterally or dorsally. Thence it 
diminishes rapidly to a width less than that of the head, and carries a foot of three 
joints, of which the first is contained within the trunk-walls, and the others are very 
small and slender, followed by a pair of furcate toes, which are of a long conical shape, 
acute, and nearly as long as the three foot-joints together. The whole foot is sometimes 
thrown up towards the belly. 
I first became cognizant of this species in October 1885, a specimen having occurred 
in sediment collected from a ditch in Sutton Park (a locality most prolific in rotiferous 
and other microscopic life) by Mr. Bolton and sent to me. The animal was dead, but 
recently ; so that the form was little altered, and the organs were all im sitw, and readily 
identified. I subsequently found a second rather smaller example in the same tube of 
water, also dead; which afforded me the advantage, always to be prized, of an additional 
study. A sight of the living animal is still a desideratum.—P.H.G.]
