172 A REVISION OF THE ASTACID.E. 



40. COLORADO. One species, C. Diogenes, from Clear Lake. I do not know in what part 



of the State this is. 



41. NEW MEXICO TERRITORY. None. 



42. ARIZONA TERRITORY. -None. 



43. UTAH TERRITORY. One species, Astacus Gambdii, from Ogden River, Ogden. 



44. NEVADA. None. 



45. IDAHO TERRITORY. One species, A. Gambdii, from Fort Hall on the Snake Eivev, 



and from the west side of Teton Basin. 



46. WASHINGTON TERRITORY. Four species: A. Klamaihensis, A. leniusculus, A. Trow- 



bridgii, and A. nigrcscens. 

 A. Klamathensis from the section east of the Cascade Range, at Fort Walla Walla, 



Wenas Valley, and Spokane Falls (upper part of the Columbia Paver 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.) 



47. OREGON. Three species : A. Klamathensis, A. leniusculus, and A. Troiobridgii.. 



A. Klamathensis. Klamath Lake ; Sikan Creek ; and Des Chutes River. 

 A. leniusculus. Lower part of the Columbia River. 

 A. Trowbridgii. Columbia River near Astoria. 



48. CALIFORNIA.* Two species : A. Klamathensis and A. nigrescens. Perhaps also 



A. Gambdii. (See page 137.) 



A. Klamathensis in Klamath Lake on the northern border of the State. 

 A. nigrescens from the neighborhood of San Francisco. 



49. ALASKA TERRITORY. One species, A. nigrcscens, from Oonalaska Island. 



50. DOMINION OF CANADA. Four species : Cambarus Bartonii (including var. robitsta), C. 



argillicola, C. propinguus, 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. propinguus. Montreal, Prov. Quebec ; Toronto, Prov. Ontario. 



A. Klamathcnsix. Streams east of Cascade Mountains, Prov. British Columbia. 



51. MEXICO. Four f species : C. Wiegmanni, Mexicanus, immunis, and Montczumce. But 



little is known concerning the distribution of these species in Mexico. The 

 only specimen of C. Mexicanus which I have seen came from Mirador. The 

 locality given by Saussure for C. Aztccus (= C. Mexicanus ?) is " Tomatlan, 

 dans les Terres-Chaudes." Von Martens records the same species from Puebla. 

 C. immunis has been found at Orizaba, C. Munti-.inna' 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. Wiegmanni, in 

 the U. S. National Museum, comes from the Isthmus of Tehuantepec. 



* In tbe U. S. National Museum there is a small specimen of Cambarus ol/scurus labelled " California" 

 (No. 2531). The locality is probably erroneous. 



f Five species, if C. Aztecus Saussure be distinct from C. Mexicanus Erichson. (See page 51.) An un- 

 described species belonging to the Parastacinse was collected by John Xantus at Colima, on the west coast. 

 This is the only Parastaeine yet discovered north of the equntor.
