HYPSILOGRAPSUS DELDENI DE MAN. 159 



Two specimens were collected in the Banda seas, botli 

 bearing a Sacculina; the distance of the external orbital 

 angles is only 7 m.m. 



14. Grapsus inacxdatus Catesby. 



We received one specimen from Liberia (Grapsus Wehhii 

 Milne Edwards), five specimens from Djeddah, Rgd Sea, 

 {Grapsus Pharaonis Milne Edwards), and three from Reu- 

 nion. The Liberia individual almost wholly agrees with 

 those from the shores of Djeddah , but in the former the 

 protogastrical lobes are somewhat less prominent and the 

 whole upper surface of the carapace and of the ambula- 

 tory legs is marked by innumerable very small yellow 

 spots. Also Alph, Milne Edwards already has united these 

 different forms under the common name of Grapsus ma- 

 culatus Catesby, regarding them as as many varieties. — 

 (Nouvelles Archives du Musee, T. IX p. 285). 



15. Grapsus gracilipes Milne Edwards. 



The Museum contains a fine male specimen , from Am- 

 boina , that almost wholly agrees with the above mentioned 

 specimens of Grapsus maculatus, var. Pharaonis from the 

 Red Sea , but dijfers by the several joints of the ainbula- 

 to7'y legs being much more slender; the upper surface of 

 the carapace and of the auibulatory legs is marked by 

 irregular yellow spots , that are not so numerous as in 

 Grapsus maculatus, var. Webbii. I am inclined to regard 

 this form as a new variety of Grapsus maculatus, Cates- 

 by and perhaps Grapsus gracilipes Milne Edwards (Annales 

 des Scienc. Natur. 1853, p. 168) will appear to be iden- 

 tical with it. 



This specimen bore a fine Bopyride in its visceral cavity. 



16. Hypsilograpsus Deldeni de Man. 



This interesting form , described by me in the Notes 

 from the Leyden Museum, Vol. I, pag. 72, 73, April
