CAMBARUS. 7 
Zoology has 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 Couesi, 
a new species of Crawfish from Dakota,” in Bull. U. S. Geolog. and Geograph. Surv. Terr., 
Vol. ILI. pp. 803, 804, deseribes C. Coues?, sp. nov., from the Red River of the North, and 
gives a note (by Dr. Coues) on the color of living (@. virilis. Types of C. Couesi have 
been received by the Museum of Comparative Zodlogy in exchange with the U.S. 
National Museum. They are not specifically distinct from C. virilis, agreeing fully with 
some of Hagen’s types of that species. 
1878. Huxley, in his essay “ On the Classification and the Distribution of the Cray- 
fishes,” Proc. Zodlog. Soc. London, 1878, pp. 752-788, gives an account of the branchize in 
a species of Cambarus obtained near Coban, Vera Paz, Guatemala, at an elevation of 
about 4,500 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. Blandingii group. Perhaps it is C. Wiegmanni Erichs. The locality is 
interesting as being the most southern on record for the genus Cambarus. 
1880-82. In the 57th Jahresbericht der Schles. Gesellsch. f. vaterl. Cultur, p. 202 
(1879), it is recorded that Dr. Gustav Joseph exhibited a blind Cambarus, @. typhlobius, 
sp. nov., from the caves of Carniola, closely related to C. pellucidus from the Mammoth 
Cave, Kentucky. In a paper published in December, 1881, in the twenty-fifth volume of 
the Berliner Eutomologische Zeitschr., the same writer again mentions the blind Crayfish 
by the name Cambarus cecus, sp. nov. (p. 257), and Cambarus 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 VIT. 
(“The Fauna of the Nickajack Cave”). This species is named Orconectes hamulatus. It 
resembles C. pellweidus 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. hamu- 
latus 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. Rep. Geolog. and Nat. Hist. Surv. of 
Minnesota, pp. 255, 254, records Cambarus virilis Hagen from Minnesota, and describes 
as a new species C. signifer, from Hennepin County, in the same State. Types of both 
of Herrick’s species have been procured through the U. 8. National Museum and 
Mr. Herrick. The “new” species, C. signifer, does not differ from Hagen’s C. immu- 
nis enough to be esteemed a different species, as was pointed out in Science, Vol. I.

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. Wisconsinensis, C. debilis, and C. gracilis, all 
of them Bundy’s species, are again described. C. acutus Gir. C. virilis Hag., C. pro- 
pingquus Gir. C. placidus Has., C. rusticus Gir., C. obesus Hag, and C. Bartonii Erichs., 
are also included in the list as Wisconsin species, C. rusticus and C. Bartonti from Lake 
Superior.
