SUMMARY OF CURRENT RESEARCHES RELATING TO 
Anatomy of Nematodes.* * * § — Dr. L. A. Jagerskiold treats of the 
digestive organs of the Nematode parasites of various fish, birds, and 
beasts, and with the glands found therein, and also the excretory organs. 
There do not seem to be sufficient anatomical distinctions to justify 
the separation of Peritrachelius from As cans. 
Australian and Fijian Nematodes.f— Mr. N. A. Cobb, in this 
memoir, which deals chiefly with Australian and Fijian Nematodes, 
describes eighty-two species, of which about half have not been hitherto 
described, and he illustrates his descriptions by more than 170 figures. 
It is stated that the edible part of three bunches of nice-looking celery 
was cut up as far as it was tender, and on washing gave 200-300 Nema- 
todes, belonging to six species, among which Mononchus longicaudatus 
was abundantly represented. A key is given to the species of Mononchus 
and of Diplogaster , another free-living, not marine genus. For Tripyla 
three keys are offered. For all these, as for a number of other genera, 
the species are fully described, and that in a way that will make the 
accounts of interest to the morphologist as well as to the systematist or 
to the student of the enemies of plants. 
y. Platyhelminthes. 
Turbellaria of ‘Albatross’ Expedition. j: — Mr. W. M‘M. Wood- 
worth states that the Turbellaria collected by the ‘ Albatross ’ were few 
in number ; Planocera pellucida being now found in the North Pacific, 
and having been known from the Indian Ocean and North and South 
Atlantic, has the widest distribution of any pelagic Planar ian now 
known. Stylochoplana calif ornica is certainly, and Prosthecerseus pana- 
mensis probably new. 
Land Planarians from Tasmania and South Australia.? — Dr. A. 
Dendy has notes on some new or little-known Land Planarians. He 
finds that the Tasmanian form, which he referred to Geoplana alba , has 
no eyes, and he proposes, therefore, to call it G. typhlops. Special atten- 
tion is drawn to the variations in marking exhibited by G. fletcheri ; 
these, though very conspicuous, are all clearly due to the intensification 
or suppression of parts of what may be regarded as the typical pattern 
of the species ; indeed, as far as the author knows, this statement holds 
good for all Land Planarians. 
Emea lacustris || — Dr. G. du Plessis gives an account of the organi- 
zation and mode of life of this freshwater Nemertine, which he has 
discovered in and near Geneva. It is one of the Enopla, and has in 
many points a close resemblance to Tetrastemma, but agrees exactly with 
Leidy’s genus Emea; indeed, its only important difference from the 
North American E. rubra is the presence of only two instead of four 
cephalic pits. From Tetrastemma the points of difference are the varia-
