ls7i'. In :i memoir " Ueber Cubanische Crustaceeu" (Arch. I'. Naturgesch., XXXYI 1 1. 

 Jahrg., Bd. I. pp. 77-147), E. v. Martens describes Cambarus Cubensis Erichs. from Cuba, 

 and Cambarus Montezuma, var. nov. tridens, from Mexico. Short diagnoses of C. Cubensis 

 Erichs., C. Wiegmanni Erichs., C. Mexieanus Erichs., C. Aztecus Sauss., and C. Montezuma 

 Sauss., are added. Concerning the identity of C. Cubensis Sauss. and C. consobrinus 

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

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

 C. Cubensis 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. Rep. Peabody Acad. 

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

 the blind Cainbari from the Mammoth and Wyandotte Caves, lie concludes that they 

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

 the atrophy of tin' visual organs. 



L873. Dr. Charles C. Abbott prints, in the American Naturalist, Vol. VII. pp. 80-84, 

 " Notes mi the Habits of certain Crawfish." The observations wore made at Trenton, 

 X. J., upon throe species, — "C. acutus Gir." [C. Blandingii), C. affinis, and C. Bartonii. 

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

 the Peabodj 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 17. S. Fish Commissioner's Report for 1.S72 and 1X73, gives a list of 

 the Astacidce of the Northern United States east of the Mississippi River (pp. 637—639). 

 This list is compiled from Hagen's Monograph, but adds new localities for C. propin- 

 quus and C. Bartonii. Orconectes inermis Cope is considered a synonym of Cambarus 

 pellucidus. . * 



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

 Inst , Vol. VI. pp. 191-200), Mr. F. W. Putnam speaks of the association of C. pell vc-id '.us 

 and C. Bartonii in the Mammoth Cave of Kentucky. The occurrence of C. pellucidus 

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

 vations are added on the color of cave specimens of C. pellucidus and C. Bartonii. 



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

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



lx7*p. "On some of the Habits of the Blind Crawfish, Cambarus pellucidus, and the 

 Reproduction oflosf Parts." ByF.W. Putnam. ProcBoston Soc. Nat. Hist., Vol. XVIII. 

 pp. 16-19. In this communication Mr. Putnam treats of the habits, coloration, exuvi- 

 ation, and restoration of lost parts in ('. pellucidus and C. Bartonii. The observations 

 were ma le 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. pellucidus lived upwards of nine months in confinement, exposed to the 

 lull glare of day. 



1S7.7 In an essay "On the Antiquity of the Caverns and Cavern Life of the Ohio 

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

 Vol I. Part I., L876), Professor X T . S. Shaler speculates on the origin of the blind 

 Cambarus pellucidus of the Mammoth Cave. (Seep. 11.
