CAMBARUS. 7 



Zoology lias obtained types of C. spinosus. It is a distinct species from any previously 

 described. 



1877. Dr. Thomas H. Streets, in an article entitled " Description of Cambarus d>i'*i, 

 a new species of Crawfish from Dakota," in Bull. U. S. Geolog. and Geograph. Surv. Terr., 

 Vol. III. pp. 803, 804, describes C. Cuu-tsi, sp. nov., from the Bed Paver of the North, and 

 gives a note (by Dr. Coues) on the color of living C. virilis. Types of C. Couesi have 

 been received by the Museum of Comparative Zoology in exchange with the U. S. 

 National Museum. They are not specifically distinct from C. virilis, agreeing fully with 

 some dl' llagen's types of that species. 



1878. Huxley, in his essay " On the Classification and the Distribution of the Cray- 

 fishes," I'roc. Zoolog. Soc. London, 1878, pp. 752-788, gives an account of the branchiae in 

 a species of Carnbarus obtained near Coban, Vera Paz, Guatemala, at an elevation of 

 about 4,300 feet above the sea. In his subsequent work, " The Crayfish," 1880, Professor 

 Huxley gives a figure of the penultimate leg of this Cambarus. It is hooked as in the 

 species of the C. Iil<ni<1iiii/ii group. Perhaps it is C. Wiegmanni Erichs. The locality is 

 interesting as being the most southern on record for the genus Cambarus. 



1 SSi i-82. In the 57th Jahresbericht der Schles. Gesellsch. f. vaterl. Cultur, p. 202 

 (1879), it is recorded that Dr. Gustav Joseph exhibited a blind Carnbarus, C. typhldbius, 

 sp. nov., from the caves of Carniola, closely related to C. pelhtcidus from the Mammoth 

 Cave, Kentucky. In a paper published in December, 1881,' in the twenty-fifth volume of 

 the Berliner Entomologische Zeitschr., the same writer again mentions the blind Crayfish 

 by the name Cumin rus ccc-cus, sp. nov. (p. 237), and Cawlxtrus Stygius, sp. nov. (p. 249). 

 In the twenty-sixth volume of the same journal, p. 12, April, 1882, Dr. Joseph gives 

 a fuller account of this species under the name Cambarus Stygius. (See p. 45 of this 

 Revision.) 



1881. A new blind Crayfish from the Nickajack Cave, Tennessee, is described and 

 figured by Cope and Packard in the American Naturalist, Vol. XV. pp. 877-882, Pl.VII. 

 ("The Fauna of the Nickajack Cave"). This species is named Orconcctcs Jiainulntux. It 

 resembles C. pcllucidus in general form, but the external sexual parts are similar to those 

 of the Cambari belonging to the C. Bartonii group. The authors surmise that 0. Itamu- 

 Intits is derived from C. latimanus. Two type specimens have been presented to the 

 Museum of Comparative Zoology by Professor Packard. 



1882. Mr. C. L. Herrick, in the Tenth Ann. Piep. Geolog. and Nat. Hist. Surv. of 

 Minnesota, pp. 253, 254, records Camlarus virilis Hagen from Minnesota, and describes 

 as a new species C. signifcr, from Hennepin County, in the same State. Types of both 

 of Herrick's species have been procured through the U. S. National Museum and 

 Mr. Herrick. The " new " species, C. signifcr, does not differ from Hagen's C. immn- 

 nis enough to be esteemed a different species, as was pointed out in Science, Vol. I. 

 p. 15, 1883. 



1882. " A List of the Crustacea of Wisconsin, with Notes on some new or little 

 known Species," by W. F. Bundy, in Trans. Wis. Acad. Sci., Arts, and Letters, Vol. V. 

 pp. 177-184. In this paper C. Stygius, C. Wisconsinemis, C. dcbilis, and C. firin-His, all 

 of them Bandy's species, are again described. C. acutiis Gir., C. virilis Hag., C. p>'o- 

 pinqims Gir., C. placid us Hag., C. rusticus Gir., C. obcsns Hag., and C. Bartonii Erichs., 

 are also included in the list as Wisconsin species, C. rusticus and C. Bartonii from Lake 

 Superior.
