CAMRARUS. 5 



In the next number of the American Naturalist, Aug., 1872 (Vol. VI. p. 404), linden 

 doubts tin 1 specific difference of the two cave forms, and opposes the establishment of a 

 now genus based on the rudimentary condition of the eyes. 



1S72. In a memoir " I'eber ( 'ubanische Crustaceen" (Arch. f. Naturgesch., XXXYI1I. 

 Jalirg., Bd. I. pp. 77-147), E. v. Martens describes /'mulx/rus Cubcnsis Erichs. from Cuba, 

 and ('a mini rufi Jf<>ii/<-.i'/iiii', vur. nov. friili'iix, from Mexico. Short diagnoses of C. Cubi-i/xi* 

 Erichs., C. II7i </////</</' Erichs., C. Mi'.i-ii-<innx Erichs., C. Aztec-us Sauss., and C. Monlczumcc 

 Sauss., are added. Concerning the identity of C. Cubcnsis Sauss. and C. consobri/mx 

 Siiuss., Von Martens is doubtful ; but lie thinks it probable, from specimens sent to the 

 Berlin Museum by Dr. Gundlach, that there is a second Cuban Cambarus agreeing with 

 0. Citbi'/ixix in the shape of the rostrum, but differing from it in the sexual appendages. 



1873. In a paper " On the Cave Fauna of Indiana " (Fifth Ann. Hep. I'eabody Acad. 

 Sci., Salem, pp. 93-97), A. S. Packard, Jr. communicates the results of a comparison of 

 the blind Cambari from the Mammoth and Wyandotte Caves. He concludes that they 

 are one and the same species, and doubts, with Hagen, the validity of a genus based on 

 the atrophy of the visual organs. 



1873. Dr. Charles C. Abbott prints, in the American Naturalist, Vol. VII. pp. 80-84, 

 " Notes on the Habits of certain Crawfish." The observations were made at Trenton, 

 N. J., upon three species, "C. acntiis Gir." (6'. Blandinyii), C. ajfuiis, and C. Burtonii. 

 Specimens of all three of these species, received from Dr. Abbott, are in the Museum of 

 the Peabody Academy of Science, Salem, Mass. 



1874. Prof. S. I. Smith, in a paper on the Crustacea of the Fresh Waters of the 

 United States, in U. S. Fish Commissioner's Report for 1872 and 1873, gives a list of 

 the Astacidss of the Northern United States east of the Mississippi Paver (pp. G37-639). 

 T liis list is compiled from Hageu's Monograph, but adds new localities for C. propin- 



and C. Burtonii. Orconcctcs inermis Cope is considered a synonym of Cambarus 



1874. In " Remarks on the Mammoth Cave and some of its Animals " (Dull. Essex 

 Inst., Vol. VI. pp. 191-200), Mr. F. W. Putnam speaks of the association of C. 



and C. Biuloiiii in the Mammoth Cave of Kentucky. The occurrence of C. 



near the entrance of another cave several miles from Mammoth Cave is noted, and obser- 



vations are added on the color of cave specimens of C. pcllucidus and C. Burtouii. 



1875. Substantially the same observations are again printed by Mr. Putnam in Proc. 

 Boston Soc. Nat, Hist., Vol. XVII. pp. 222-225. 



1875. "On some of the Habits of the Blind Crawfish, Cambarus pellucidus, and the 

 Reproduction of lost Parts." By F. W. Putnam. Proc. Boston Soc. Nat. Hist., Vol. XVIII. 

 pp. 1G-19. In this communication Mr. Putnam treats of the habits, coloration, exuvi- 

 ation, and restoration of lost parts in C. peHiu-idus and C. Bartonii. The observations 

 were made upon living specimens, brought to Cambridge, Mass., from the Mammoth Cave. 

 The specimens are now preserved in the Museum of Comparative Zoology. One of the 

 specimens of C. pcllucidus lived upwards of nine months in confinement, exposed to the 

 full glare of day. 



1875. In an essay " On the Antiquity of the Caverns and Cavern Life of the Ohio 

 Valley" (Mem. Boston Soc. Nat. Hist., Vol. II. p. 362; also in Mem. Ky. Geolog. Surv., 

 Vol. I. Part I., 1876), t Professor N. S. Shaler speculates on the origin of the blind 

 Cambarus p<11 nt-idi/* of the Mammoth Cave. (See p. 41.) 



1875. Erocchi, in his "Recherches sur les Organes Genitaux Males des Crustace's 

 Ddcapodes" (Ann. Sci. Nat, 6 e S6rie, Zool. et Paleontol, Tom. II. Art. 2), figures the first
