172 A REVISION OF THE ASTACID.E. 



40. CoLOEADO. — One species, G. Diogenes, from Clear Lake. I do not kuow in what part 



of the State this is. 



41. New Mexico Territory. — None. 



42. Arizona Territory. — Noue. 



43. Utah Territory. — One species, Astacus Gambelii, from Ogden I>iver, Ogden. 



44. Nevada. — None. 



45. Idaho Territory. — One species, A. Gambelii, from Fort Hall ou the Snake River, 



and from the west side of Teton Basin. 

 4G. Washington Territory. — Fonr s^jecies : A. Klamathensis, A. lenmsculus, A. Trow- 



hridr/ii, and A. ni(jre.sce)is. 

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



Wenas Valley, and Spokane Falls (ujiper part of the Columbia lUver and 



tributaries). 

 A. leniiiscuhis from the lower part of the Columbia River and Puget Sound. 

 A Trowhridgii. Lower part of Columbia River, near Astoria ; streams running 



into Shoalwater Bay. 

 A. nigrcscens. Fort Steilacoom on Puget Sound. (See page 135.) 



47. Oregon. — Three species : A. Klamathensis, A. leniusculus, and A. Trowhridgii.. 



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

 A. leniuseulus. Lower part of the Columbia River. 

 A. Trojvbridgii. Columbia River near Astoria. 



48. California.* — Two species : A. Klamathe7isis and A. nigrescens. Perhaps also 



A. Gamhelii. (See page 137.) ^

 A. nigrcscciis from the neighborhood of San Francisco. yj.-''j C(yvcW-<\^ z-) ■■■■■X:*^  



49. Alaska Territory. — One species, A. nigrescens, from Oonalaska Island. 



50. Dominion of Canada. — Four species : Cambarus Bartonii (including var. robusta), C. 



argillieola, C. propinquus, and Astacus Klamathensis. C. Diogenes, which occurs 

 at Detroit, Mich., will doubtless be found ou 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. argillieola. Toronto, Prov. Ontario. 



C. propinquus. Montreal, Prov. Quebec ; Toronto, Prov. Ontario. 



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

 61. Mexico. — Four f species : G. Wiegmanni,3Iexieanus,imniiaiis,aiK\ Montezuma;. But 

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

 only specimen of G. Mexicamis which I have seen came from Mirador. The 

 locality given by Saussure for G. Aziccus (= Q. Mexicamis ?) is " Tomatlan, 

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

 C. immunis has been found at Orizaba, G. Montezumcc 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 G. Wicgmanni, in 

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



* In tbc TJ. S. National Museum there is a small specimen of Cambarus oLscurus lal)elled "California" 

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



f Five species, if C. Azteciis Saussure be distinct from C. Mexieanus Ericbson. (See page .51.) An un- 

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

 This is the only Parastaciiie yet discovered north of the eqiictor.
