On Manayunkia. 
Prof. Leidy made some remarks on a specimen of Manayunkia, 
of which he exhibited a drawing, and which had been recently 
obtained by Mr, Edward Potts, from the mill-pond of Absecom 
Creek, at Absecom, N. J. It was of especial interest as appa- 
rently confirming the freshwater habit of a cephalobranch annelide. 
The worm was contained in a tube attached to the midrib of a 
decayed leaf, to which there were attached several similar but 
empty tubes about 1 line long. The worm, 1°5 millim. long, 
appears to be an immature form of Manayunkia speciosa. The 
body consists of ten setigerous segments succeeding the head. 
The latter supports two lophophores, each with ten tentacles, of 
which none are conspicuously larger than the others. A pair of 
eyes occupy the head, but no pigment spots exist along the base of 
the tentacles. The podal sete are from two to four, but mostly 
three, on each side of the segments. The podal hooks, but one on 
each side of the setigerous segments, except the first of the latter, 
which has none; and the last two, which have rows of six comb- 
like hooks on each side. The worm is translucent white, and the 
blood very pale green. 
Ordinarily, Absecom pond is purely fresh water, and contains in 
abundance the usual plants and animals characteristic of fresh 
waters. Mr. Stuart Wood stated that in occasional extreme high 
tides of Absecom Creek, the pond had been subjected to the overflow 
of salt water—Proc. Acad. Nat. Sci. Philad., Dec. 1883, p. 302. 
On a Mediterranean Species of Lingulinopsis. By Dr. L. G. 
BornEMANN, Jun. 
In 1860 Reuss established the genus Lingulinopsis for a Forami- 
niferan intermediate between the families Rhabdoidex, Glanduli- 
nid, and Cristellaroidee. He referred to this genus the form 
previously described by him under the name of Lingulina bohemica 
from the Pliner near Teplitz. Subsequently Schwager united with 
it Amphistegina striata, Reuss, from the Neocomian of Westphalia. 
The author now records the occurrence off Carloforte (in the island 
of San Pietro, Sardinia) of a recent species of the genus, for which 
he proposes the name of Lingulinopsis carlofortensis. It is a rather 
large species, over 5 millim. long, and lives in great abundance on 
the beds of coral in the above locality — Att: della Soc. Toscana di 
Sci. Nat., Mem. vol. vi. p. 26.
