28 AilPniPoUA NORMALIA. 



and lUtorea, in the ^luseum ot the Jardin dcs riantes, I could 

 perceive no fcatiu'c that would justify a separation of them from 

 the same spoeies. M. Lucas also most kindly allowed me to examine 

 those that he brought A^ath him from iygeria ; and again I felt con- 

 vinced that those which he has named 0. Mo)itac/ui, in his great 

 and vahiable Avork, are identical with the types of Montagu's spe- 

 cimen preserved in the British Museum. 



18. Orchestia Bottae. 

 Orcliestia Bottge, Edwards, Hist. Nat. Crust, t. iii. p. 17. 



This appears to be a very doubtful species. The only distuaction 

 which M. Edwards perceived between it and Orchestia sauteuse 

 (littorea'?) is one that is dependent upon age — the last pair- of pereio- 

 poda are not broadly develoi^ed. Tliis being a character that is not 

 present imtil after the male has attained its full dimensions, it can 

 scarcely be accepted as the definition of a separate species. 



I have previously stated having come to the conclusion, after 

 examining the specimens in the Museum of the Jardin des Plantes, 

 that 0. Montagui of Audouin is identical Avith 0. littorea of Montagu ; 

 0. Bottne, the author says, is very much hke 0. littorea ; and 

 Egypt is given by Savigny as the habitat of 0. Montagui ; we may 

 therefore assume that 0. Bottoi is the young form of that species : 

 but there is one circumstance that must cause us to hesitate before 

 pronovmcmg it certain — 0. littorea belongs to the Mediterranean, 

 whereas 0. Bottce Kves on the shores of the Red Sea. 



The original specimen not being preserved, the name can only 

 be retained by coui'tesy, until opportunity occurs for a more extended 

 examination of the Orchesticv of the eastern shores of Egypt. 



" Krauss mentions that the 0. Bottce, Edwards, is found in South 

 Afi-ica, at Port Natal*."
