LIST OF CRUSTACEA COLLECTED. 
[By Mary J. Rathbun, Department, of Marine Invertebrates, National Museum.] 
The collection of Crustacea of which a list is given below was made by Prof. 
B. W. Evermann, of the U. S. Fish Commission, during the months of November and 
December, 1891, while engaged in an investigation of the fresh and salt waters of 
eastern Texas, with a view to the establishment of a hatchery. While the collection 
contains no new species, it is interesting from the fact that it extends the limits of 
many species and furnishes new localities for others. Those species which have not 
been hitherto recorded from a locality so far south, are as follows: Panopeus depressus , 
Gallinectes hastatus, Tozeuma carolinensis , Palcemonetes vulgaris , Palcemonetes exilipes , 
Palcemon ohionis. PLippa emerita (not talpoida Say) has not been found further north 
than Cuba and Mexico. The species whose range includes Texas but which have not 
been previously recorded from there, are Libinia dubia , Panopeus herbstii , Arenceus 
cribrarius , Petrolisthes armatus , A Ipheus heterochwlis, and Squilla empusa.

the following characteristics: The median lobe of the front is more triangular; the 
lateral lobes much longer and narrower. Second joint of outer antennae with the 
median spine very long, much exceeding the eyes, directed slightly outward; while in 
talpoida the spine is much shorter and directed inward. Third point of outer maxil- 
lipeds longer and narrower than in talpoida , the inner margin being straight or 
slightly concave for its anterior two-thirds instead of convex as in talpoida ; the lobe
