CAMBAEUS. 7 



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

 described. 



1877. Dr. Thomas H. Streets, in an article entitled " Description of Camharus Coitesi, 

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

 Vol. III. pp. 803, 804, describes C. Covcsi, sp. nov., from the Eed Eiver of the North, and 

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

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

 National Museum. Tliey are not specifically distinct from C. virilis, agreeing fully ^\■ith 

 some of Hagen's types of tliat species. 



1878. Hu.xlev', in his essay " On the Classification and the Distribution of the Cray- 

 fishes," Proc. Zoolog. Soc. London, 1878, pp. 752-788, gives an account of the branchiie in 

 a species of Cambarus obtained near Coban, Vera Paz, Guatemala, at au elevation of 

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

 Hu.xley 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 Jahre.sbericht der Schles. Gesellsch. f. vaterl. Cultur, p. 202 

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

 sp. nov., from the caves of Carniola, closely related to C. iicllucidus from the Jlammoth 

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

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

 by the name Camharus emeus, sp. nov. (p. 237), and Camharus Stygius, sp. nov. (p. 249). 

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

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

 Eevision ) 



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 Orconcctcs liamulatus. It 

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

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

 latus is derived from C. latimamis. Two type specimens have been presented to tlie 

 Museum of Comparative Zoology by Professor Packard. 



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

 Minnesota, ]ip. 253, 254, records Camharus 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 througli the U. S. National Museum and 

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

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

 p. 1.5, 1883. 



1882. " A List of tlie Crustacea of Wisconsin, witli Notes on some new or little 

 known Species," by W. F. Bundy, in Trans. Wis. Acad. ScL, Arts, and Letter.?, Vol. V. 

 pp. 177-184. In this paper C. Stygius, C. Wiscotisincnsis, C. dchilis, and C. gracilis, all 

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

 pinquus Gir., C. placidus Hag., C. rusticus Gir., C. ohesus Hag., and C Bartonii Erichs., 

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

 Superior.
