CoLorabo. — One species, C. Diogenes, from Clear Lake. I do not know in what part 
of the State this is. 
New Mexico Terrirory. — None. 
Arizona Territory. — None. 
Uran Trerrirory. — One species, Astacus Gambelit, from Ogden River, Ogden. 
Nevapa. — None. 
Ipano Terrirory. — One species, A. Gambelii, from Fort Hall on the Snake River, 
and from the west side of Teton Basin. 
WasHINGToN TERRITORY. — Four species: A. Klamathensis, A. leniusculus, A. Trow- 
bridgii, and A. nigrescens. 
A. Klamathensis from the section east of the Cascade Range, at Fort Walla Walla, 
Wenas Valley, and Spokane Falls (upper part of the Columbia River and 
tributaries). 
A. leniusculus from the lower part of the Columbia River and Puget Sound. 
A Trowbridgii. Lower part of Columbia River, near Astoria; streams running 
into Shoalwater Bay. 
A. nigrescens. Fort Steilacoom on Puget Sound. (See page 135.) 
Orecon. — Three species: A. Klamathensis, A. leniusculus, and A. Trowbridgit.. 
A. Klamathensis. Wlamath Lake; Sikan Creek ; and Des Chutes River. 
A. leniusculus. Lower part of the Columbia River. 
A. Trowbridgvi. Columbia River near Astoria. 
Catirornia.* — Two species: A. Klamathensis and A. nigrescens. Perhaps also 
A. Gambelit. (See page 137.) 
A. Klamathensis in Klamath Lake on the northern border of the State. 
A. nigrescens from the neighborhood of San Francisco. 
ALASKA Trerrirory. — One species, A. nigrescens, from Oonalaska Island. 
Dominton or CANADA. — Four species: Cambarus Bartonti (including var. robusta), C. 
argillicola, C. propinquus, and Astacus Klamathensis. C. Diogenes, which occurs 
at Detroit, Mich., will doubtless be found on the Canadian side of the river. 
C. Bartonii. St. John, Prov. New Brunswick; Montreal, Prov. Quebec ? 
C. Bartonii, var. robusta. Toronto and Weston, Prov. Ontario. 
C. argillicola. Toronto, Prov. Ontario. 
C. propinquus. Montreal, Prov. Quebee ; Toronto, Prov. Ontario. 
A. Klamathensis. Streams east of Cascade Mountains, Prov. British Columbia. 
Mexico. — Four} species: C. Wiegmanni, Mexicanus, immunis, and Montezume. But 
little is known concerning the distribution of these species in Mexico. The 
only specimen of (. Mexicanus which I have seen came from Mirador. The 
locality given by Saussure for C. Aztecus (= C. Mexicanus ?) is “Tomatlan, 
dans les Terres-Chaudes.” Von Martens records the same species from Puebla. 
C. immunis has been found at Orizaba, C. Montezwme in the neighborhood of 
the city of Mexico, at Puebla, Parras in the State of Cohahuila, and at Mazat- 
lan on the Pacific coast. A mutilated specimen, probably C. Wiegmannd, in 
the U.S. National Museum, comes from the Isthmus of Tehuantepec. 
* In the U. S. National Museum there is a small specimen of Cambarus obscurus labelled “ California” 
(No. 2531). ‘The locality is probably erroneous. 
+ Five species, if C. Aztecus Saussure be distinct from C. Mexicanus Erichson. (See page 51.) An un- 
described species belonging to the Parastacine was collected by John Xantus at Colima, on the west coast. 
This is the only Parastacine yet discovered north of the equator.
