^ Dr. Heller, in his preliminary account of the Crustacea collected by 

 the Novara Expedition (Verbandl. Zool. Bot. Gesellscbaft, Wien, 1862, pp. 

 519-528), characterizes several genera and species of which no mention is 

 made in the final report. These are MenmtJiius brevirostris which is prob- 

 ably Acantlionyx consobrinus A. Edw. , of the final report ; Xantho tetraodon 

 is Eudora tetraodon, Carpilodes granulatus appears to be C. tristis Dana. 

 Lupa Mrsuta was probably referred to Neptunus sanguinolentus. Thel- 

 phusa willlerstorfl appears to be /. leschenmidii, Parathelphusa dentipes to be 

 P. tridentata, Eelcecius areolatus to be H. cordiformis, Metaplax Jiirtipes is 

 apparently referred to a new genus, Orapsus depressus is probably Oeo- 

 grapsus crinipes, Orapsus dedivifrons is apparently rechristened Pachygrap- 

 sus iniermedius, Eeterograpsus barbigerus has its specific name altered 

 to barhimanus, Epigrapsus nov. gen. reappears as Nectograpsus nov. 

 gen. with no reason assigned for the change. Metasesarma granulatus is 

 redescribed as new under the name rugulosa. Plagusetes elatus is prob- 

 ably, as pointed out by Mr. Miers (Ann. and Mag. Nat. Hist., ix, p. 147, 

 1878), Acuntliocydus gayiof the final report. Oelas^m^ls vcmegatus appears 

 to have been finally referred to G. annulipes. Palinurus paulensis was 

 afterward apparently referred to P. lalandii and Pelias notatus is refen-ed 

 to Anchistia. All this shuffling of names is made without the slightest hint 

 to aid one in correlating the two papers, and is a proceeding which cannot 

 be too strongly condemned. 



- There were at least two editions of Catesby bearing dates as above, 

 and as the second appeared thirteen years after the tenth edition of the 

 Syslema Natures oiJAmw, and five after the twelfth edition, the names em- 

 ployed by Catesby will hold.
