Vortex lemani, Du Pless. [Zool. Rec. xi. p. 601] (rediscovered in the Starn- 
berger Lake in Bavaria), is most nearly allied to the freshwater Planarians, 
and is named by Graff (3), provisionally, Planaria lemani. It probably 
will be the type of a separate family ; with the Rhahdoccela it has no 
relationship, though it has not the ramified intestine of the Dendrocoda. 
The same author (2) describes anatomically several new Turhellaria ; 
Planaria quadri-oculata^ Gr., p. 419, pi. xxviii, figs. 21-23 (Lake Starn- 
berg), Meaostomum hanaticum^ Gr., p. 418, ih. figs. )9 & 20 (Panczova), 
M. montanum, Gr., p. 417, ih. figs. 12-18 (Mummelsee, Schwarzwald), 
Prostomum hanaticum^Qv,, p. 415, pi. xxvii. fig. 11 (Panczova); also 
Stenostomum leucops, Schm,, and Microstomum lineare, Orst. 
Moseley (11) characterizes the Geoplanidcje thus; “Corpus elongatum, 
depressum vel depressiusculum, subtus pede sat distincto ; caput con- 
tinuum vel discretum ; ocelli duo vel plurimi in capjte solum aut etiam 
passim in corpore dispositi ; os postmediale ; oesophagus protractilis, 
.campanulatus, margine ssapius sinuoso, aut doliiformis; apertura geni- 
talis pone os.’' The known species of Geoplana^ Bipalium (= Sphyro- 
cephalus, Schmd.), and Rhynchodemus (“ Planaria terrestris ”) are enu- 
merated, biological observations recorded, and 2 new species described, 
viz., Bipalium ceres, p. 109, pi. x, figs. 1 & 2, and Rhynchodemus 
thwaitesi, p. Ill, pi. x. fig. 4, both from Ceylon; a young B. diana, 
Humb., is also figured (pi. x. fig. 3), Bipalium uses a thread of its 
tough investing slime for suspension in air, and lets itself down to the 
ground from a twig, in this manner. 
McIntosh (6) has examined 2 species of Balanoglossua (pp. 144-150), 
and institutes an interesting comparison between this type and the 
Nemertinea, The most marked differences are in the nervous system, 
and in the want of the true Nemertean “ proboscis,”
