QUARTERLY CHRONICLE. Gi 
Icthydium, bears, he states, a very close resemblance to the 
larva of the Annelid Lysidice, which he has observed at 
Naples, and which will be more fully described at a future 
time with other Annelid-larve. He gives, as his final opinion, 
that Dinophilus (and hence, we suppose, the allied groups, 
Cephalotricha and Gasterotricha generally) is to be regarded 
as a stationary Annelid-larva, bearing the same relation to 
Annelida as Appendicularia to the Ascidians—the view ori- 
ginally put forward by Professor Huxley in this Journal. 
“ On a Fresh-water Crustacean in the Nile,’ by Dr. C. B. 
Klunzniger. 
“On the Kidneys of Tropidonotus natrix and of the Cypri- 
noids,” by O. Gampert.—This is a short paper, with a well- 
drawn plate, by a pupil of Professor Frey. A few interesting 
notes are given on the structure, dimensions, &c., of the tubuli 
and vessels of the kidney in the commonring-snake and carps. 
“On Cohnheim’s ‘ Compartments’ in the Cross-section of 
Muscles,” by A. Kolliker.—This paper relates to the arrange- 
ment of muscular tissue in separate bundles, which Dr. Cohn- 
heim, in ‘ Virchow’s Archiv’ for 1865, described at some 
length, making his observations by freezing the muscle and 
cutting it across the fibre, when a mosaic-like disposition be- 
comes apparent. Professor Kélliker had misunderstood this 
structure in 1856, and now returns to its study with the im- 
proved instrument of 1866. He concludes, from numerous 
considerations adduced, that the muscular bundles possess 
really a fasciculate (faserigen) structure, or that the parts 
which bind together the sarcous elements in the longitudinal 
direction have not the same character as the cross-binding 
middle portion and the substance between Cohnheim’s 
“compartments ;” also that the muscular columns (muskel- 
aulchen) are still further held together, and consist of fibrillee 
and very scanty intervening substance. In another part of 
our Chronicle is an abstract of some notes by Dr .McNamara 
on the same subject. 
Max Schultze’s Archiv f. Mikr. Anat. Second and Third 
Parts, 1866.—The bulk of this double number is occupied 
by a paper by Professor Schultze ‘‘ On the Retina,’ of which 
-a long notice is given among our translations. The other 
memotrs in this number are— 
“ Contributions to the Natural History of the Infusoria,” 
by Dr. W. Zenker. 
“ Description of a Live-box for the observation of Living 
Tadpoles and other Animals,” by F. E. Schultze, of Rostock. 
“On the Sculpture of Gyrosigma,” with a plate, by M. 
Schiff, of Florence.
