742 ` The American Naturalist. [August, 
into which the water of the estuary overflows but cannot return to the 
river. This wateris brackish and contains a few sea fish, among 
which are some whitebait and herring. These fish thrive and repro- 
duce themselves, but are reduced in size and are gradually forming a 
dwarfed species, especially the herring. These brackish water fish 
could easily be utilized for pisciculture. Mr. Yarrel reports that the 
whitebait adapts itself to fresh water where it grows and multiplies 
almost as well as in the sea, furnishing a table fish which for size and 
flavor is not surpassed by its salt water relatives. (Revue Scientifique 
June, 1893). 
Invertebrata.— Dr. J. G. de Man has recently published in quarto 
form full descriptions of 129 species of Decapods found in the Indian 
Archipelago. Amongthem the author notes 27 new species and 9 new 
varieties. They are all classified under 50 genera. Fourteen plates, 
and a table showing the geographical distribution of the fresh water 
species accompany the paper. (Zool. Ergeb. einer Reise in Neiderl. 
Ost. Indien, Zweiter Bd., Leiden, 1892). 
According to Dr. M. Weber 112 species of fresh-water crustaceans 
have been found in the Indian Archipelago, of which 88 are Decapoda, 
10 Isopoda, 6 Ostracoda, 5 Cladocera, 4 Amphipoda, 2 Copepoda, 1 
Branchiura and 1 Branchiopoda. (Zool. Ergeb. einer Reise in Niederl. 
Ost. Indien, Zweiter Bd. Leiden, 1892). 
Vertebrata.—Mr. J. A. Allen reports 17 mammals and 162 birds 
collected in northeastern Sonora and northwestern Chihuahua, Mexico, 
on the Lumholtz Archeological Expedition 1890-92. Of the 
birds 12 species occur as resident birds within 150 miles of the south- 
ern border of the United States. (Am. Mus. Nat. Hist., March, 1893). 
A summary of the species of Reptiles and Batrachians of Wisconsin 
published by Prof. W. K. Higley gives Lacertilia 4, Ophidia 22, 
Testudinata 13, Anura 8, and Urodela 12. Among the turtles is 
mentioned Macrochelys lacertina, the Loggerhead Snapper which the 
author says is occasionally found in the Mississippi River as far north 
as the mouth of the Wisconsin. (Wis. Acad. Sci. and Arts, Vol. 
VID).
