and figured by Mr. Backhouse in the 4 Journal of the 
Geological Society,’ in 1886. It was purchased for the Dublin 
Museum at £14 14s. Among the specimens dredged from the 
North Sea were an Eleplias femur of gigantic size, £1 10s. : 
and the lower jaw with teeth of a Rhinoceros, £1 5s. The 
mammalian and other remains from the Norfolk Forest-Bed 
included two lower jaws with teeth of Rhinoceros etriiscus. 
£1 12s. 6d. and £1 is. ; and an exceptionally fine skull with 
parts of both antlers of Ccrvus verticornis, £3 15s. Among 
the specimens from the Red Crag of Suffolk were a number 
of teeth of Mastodon arvennensis, which varied from £1 to 
£3 per lot. 
Notes on the Floscularia of the Great Yarmouth 
District, Read April iqth, 190 7: — For several years past 
I have searched for this beautiful fixed Rotiferon in the 
waters of the Great Yarmouth district, and have been success- 
ful in finding them year bv year in the same localities, which 
include the following : — West Caister (next Caister-on-Sea). 
Gt. Ormesby. Burgh Castle (in private lake). Southtown 
Marshes. Gt. Yarmouth. Fritton Lake. Lound Run. 
So far my collections include three species, viz.: — Floscularia 
ornata, F. cornuta, and F. ambigua. 
The animal has a great predilection for various mosses 
growing at the borders of some of the cleaner ditches, and 
loves to ensconce itself in the hollows of the boat-like leaves 
of these tiny plants. One year I found F. ornata in good 
quantity on some floating moss in Fritton Lake : these were 
specially beautiful on account of the absolute transparency 
of their bodies — a condition peculiar to most lacustrine 
Rotifers. These have generally been associated with Philodina. 
Rotifer vulgaris and similar forms, but are somewhat awkwardly 
placed on account of being partly hidden in the leaf hollows. 
The water plant par-excellence upon which to find the Floscule 
is Myriophyllum which grows in dense masses in the brackish 
ditches in the vicinity of the mouth of the Yare, where there 
is a net work of these useful water-ways used for draining the 
marshes. I have found this “ weed ” in all parts of Norfolk
