more or less inaccessible and most of it closet made. So far as 
the reviewer can see, O. woodwardi is a valid species. It is well 
figured by Mr. Waite. 
In the Revista do Museu Paulista, Dr. Carl H. Eigenmann and 
Allen A. Norris record (in Portuguese) species of fishes collected 
by Dr. H. von Ihering about Santos, in the Province of Sao Paulo. 
The following are described as new: Mannoglanis bifasciatus, Impar- 
Jinis piperatus, Geldiella (eques) (new genus), Lheringichthys (labrosus), 
Bergiella (westermanni), Perugia (agassizii), Parodon tortuosus, Tetra- 
gonopterus multifasciatus, Catabasis acuminatus, Myletes tieté. Of the 
new genera, Imparfinis is an ally of Rhamdiella; and Catabasis 
of Salminus. The others are based on known species. 
Dr. Carl H. Eigenmann sums up his researches on the degenera- 
tion of Amblyopsidz and the reaction of blind-fishes to light in a 
lecture before the Marine Biological Laboratory at Woods Holl, 
published by Ginn & Company (1900). He regards the bleaching 
due to absence of light as an acquired character which is now fully 
inherited. “It is evident that in Amblyopsis we have the direct 
effect of the environment on the individual hereditarily established.” 
In the Anatomischer Anzeiger (XVII, p. 313), Professor George 
H. Parker has a valuable study of the blood vessels of the heart of 
the headfish or sunfish (Mola mola). He finds that, unlike most 
bony fishes, this species has retained in part the complex structures 
found in the Elasmobranchs, without the simplification or degradation 
seen in the ordinary bony fishes. When anatomists realize that not 
all bony fishes agree even in important characters, they will not so 
generally confine their studies in fish anatomy to the primitive end 
of the fish series. There is no more open field in science than that 
of the structure and development of the different groups of Teleost 
fishes. D. S. J. 
The ** Tierreich ’? Sporozoa.!— The work opens with a summary 
of abbreviations of technical terms and one for the literary references, 
together with a systematic index. The taxonomic survey of the vari- 
ous genera and species of the group, which occupies the major 
portion of the book and follows the general plan employed in the 
publication as a whole, is complete and better illustrated than some 
previous numbers. After this comes a list of hosts, which embraces
