298 Rmiella ffranifera, ham. Acapulco. 



299 Murex radix, Gme\. Acapulco. 



300 Murex tricolor, Yal. = M. reffius. Swains, (recte). 



301 Murex bicolor, Yul. := M.i-epius, Schuh. 8i Wagn. {male). "Vf'ith 



the last at Acapulco." 



302 Murex erinaceoides, Val. Acapulco. 



This list, being the largest known from Acapulco, would have been ex- 

 tremely valuable, could it have been depended on for accuracy. But (1) the 

 presence of several well-known E. Indian and other foreign shells (supposed 

 by Prof. Adams to have been obtained from the inhabitants, the relics of 

 former trade with the Philippines) endangers the authenticity of others, 

 unless there be further confirmation. And (2) the description of the species, 

 although set forth with not a little display, is performed in so loose a man- 

 ner, that it is impossible to speak of them with confidence without an inspec- 

 tion of the types. It will be seen that the author adopts a course, too com- 

 mon among French naturalists, of changing the specific when he alters the 

 generic name, appending his own authority for the species ; and that when 

 two authors have used the same name for a shell, instead of preserving the 

 right and re-naming the wrong, he has given his own names to both .species. 



25. In the " Voyage autour du Monde sur la Coquille, pendant les annees 

 1822-,5, par L. I. Duperrey, Paris, 1826" (plates only), the following are the 

 only two species connected with this province : — 



" Moll. pi. 11. f. 1, 1', Natica glauca, Humb. Peru :" =: iV. patula. Sow. 

 "Moll. pi. 15. f. 2, 2 A, Calyptrcea Adolphei, Less.," has the animal _<j{*esented 

 in the reversed position : = Crepidula dilatata. Lam. 



From the text (not seen) are quoted, among others — 



P. 421. No. 198 (1830), Patella scurra. Less. 

 P, 419, Patella clypeaster. Less. 



26. The earliest known collector on the North-west shores of America 

 was the justly celebrated Dr. Johann Friedr. Eschscholtz, Professor and 

 Director of the Zoological Museums in the University of Dorpat. He ac- 

 companied an expedition in the Russian ship Predpriaetie, commanded by 

 Capt. Kotzebue, during the years 1823-6, which, after sailing round Cape 

 Horn, and visiting the Bay of Conception in Chili, proceeded by the Sand- 

 wich Islands to Kamtschatka, reaching Petropaulovski June 22, 1824'. 

 Thence they proceeded along the north-west coast of America to Sitcha, and 

 in October and November to San Francisco and the Rio Sacramento, In 

 the following year they again sailed by the Sandwich Islands to Norfolk 

 Sound, Sitcha ; thence to Manilla ; and returned via St. Helena. During 

 this time Eschscholtz collected 2400 species belonging to all divisions of the 

 animal kingdom ; including 10 sp. of Cephalopoda, 172 Gasteropoda, 45 

 Lamellibranchiata, and 28 Tunicata*. The description of the new species 

 was commenced by Eschscholtz in the " Zoologischer Atlas, enthaltend Abbil- 

 dungen und Beschreibuugen neuer Thierarten, Berlin, May 1829 ;" but he 

 died of nervous fever. May 7, 1831, at the early age of 37 years. The work 

 was brought to a conclusion in the year 1833 (from the author's MSS.) by 

 Dr. Martin Heinrich Rathke, who appears to have succeeded him in the 

 chair at Dorpatf. The following is the brief list of the species bearing on 



* The plants collected during the expedition appear to have been described by Eschscholtz 

 immediately after his return, in the Memoires de I'Acad. de St. Petersbourg, vol. x. p. 281— 

 292 (1826), " Descriptiones plantarum novae Californise, adjectis florum exoticorum analysibus."
