CAMBARUS. 7 



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

 described. 



1877. Dr. Thomas II. Streets, in an article entitled " Description of Cambarus ( 



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

 Vol III. pp. 803, 804, describes C. ( 'ouesi, sp. dov., from the Red River 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 of Hagen's types of thai species. 



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

 fishes," Proa Zoolog. Sue. London, 1878, pp. 752-788, gives an account of the branchiae in 

 a species of Cambarus obtained near Cuban, 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 O. 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. now, 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 ccecus, sp. nov. (p. 237), 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 

 b'e\ ision.) 



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, PI. VII. 

 ("The Fauna of the Nickajack Cave"). This species is named Orconectes hamulatus. It 

 resembles C. pellucidus 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. 



L882. Mr. C. L. Herrick, in the Tenth Ann. Pep. Geolog. and Nat. Ili.t. Surv. of 

 Minnesota, pp. 25.°,, 254, records Ca „ihn rus virilis Hagen from Minnesota, and describes 

 as a new species C. signi/er, from Hennepin County, in the same Slate. Types of both 

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

 Mr. Herrick. The "new" species, C. signi/er, does not differ from Hagen's ('. immu- 

 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. V I'.und.v. in Trans. Wis. Acad. Sci, Arts, and Letters, Vol. V. 

 pp. 177-184. In this paper 0. Stygius, C. Wisconsinensis, C. debilis, and C. gracilis, all 

 of them Bundy's species, are again described. C, acutus Gir.. G. virilis Bag., C. pro- 

 pmquiu Gir., C. placidus Hag., C. rustieus Gir., C. obesus Hag., and C. Bartonii Erichs., 

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

 Superior.

 Species of Cambarus," by W. F. Bundy, in Geology of Wisconsin, Survey of L873-79,
