INTRODUCTION. 



BIBLIOGRAPHY. 



The following are the chief works and papers in which 

 will be found accounts of the Crustacea of Devon and 

 Cornwall. 



PENNANT (THOMAS). British Zoology, vol. iv. 1777. 



Forty-four species are recorded by the Author as British. Among 

 these is one of great interest, his Cancer arctus, p. 17, of which he 

 writes " Found by Dr. Borlase on Craig Killas in Mounts Bay." This 

 is clearly Arctus ursus, Dana (this work, p. 13), which has generally 

 been supposed to have been first added to the British Fauua by 

 Jonathan Couch in 1862. 



MONTAGU (GEORGE). In the papers of this excellent zoologist are 

 descriptions of many Crustacea which he added to the British 

 Fauna from the Devonshire Coast, where his chief hunting-ground 

 was Salcombe. Traus. Liuu. Soc. vol. vii. 1804, pp. 61-85, pis. vi., 

 vii. ; vol. ix. 1808, pp. 84-114, pis. ii.-viii. ; vol. xi. 1813, pp. 1-26, 

 pis. i.-v. ; and same volume, 1815, pp. 179-204, pis. xii.-xiv. 

 LEACH (WILLIAM ELFORD) described many species from Devon and 

 Cornwall in his articles on the Crustacea in: (1) The Edinburgh 

 Encyclopaedia, vol. vii. (1813 ?), Article " Crustaceology." (2) The 

 Edinburgh Encyclopaedia, Appendix, vol. vii. 1814, " Crustaceology," 

 pp. 429-437. (3) Trans. Liuu. Soc. vol. xi. 1815, pp. 30G-400. 

 (4) Encyclopaedia Britannica Supplement, 1816, " Anuulosa," 

 pp. 401-453. 



LEACH (WILLIAM ELFORD). " Malacostraca Podophthalmata Bri- 

 tanuiaj," 1815. Among the forty-four very fine plates are many 

 illustrations of species from Devon and Cornwall, collected by 

 Crunch, Prideaux, Moore, Gibbs, Montagu, and Leach himself. 

 COUCH (JONATHAN). A Cornish Fauna. Pt. I. Vertebrata, Crus- 

 tacea, and a portion of the Kadiate Animals. Royal Institution of 

 Cornwall, Truro, 1838. 



Couch's catalogue of Crustacea contains 54 species (viz., Bra- 

 chyura 34, Anomura 5, Macrura 13, Scluzopoda 1, Stomatopoda 1). 

 Among the species are : 



(a) Cancer incisocrenatus, n. sp., p. 69, which would seem to be 

 a very young stage of Cancer f>fif/urus. 



(ft) Gelasimus Bellii, n. sp., p. 72, regarded by Prof. Bell as the 

 female or young male of Gonoplax finffiilata. 



(c) Genus Autonomea (p. 79). " Eyes on short footstalks, project- 

 ing from beneath the border of the carapace. The snout scarcely 

 passing beyond the eyes. The inner antennse double, one filament 

 much longer than the other. Outer antenna? slender, and much 

 longer than the body. Front pair of legs only with hands.
