68. PODOPHTHALMOUS CRUSTACEA, 



the posterior ambulatory legs however are short , not slender 

 and are also ornamented with dark lines. 



Breadth of carapace (of the female) 24 m. m. 

 Length » ' 20 m. m. 



The space between the orbits measures 9 m. m. 



This interesting species has been collected by Mr. Hoedt 

 at Amboina. 



16. Grap sus Pelii Herklots. 



Herklots. Addit. ad Faun. Afr. p. 8. Milne Edwards , 

 Ann. Scienc. Nat. t. XX, 1853, p. 166. 



This species is identical with Goniopsis cruentatus Latr. 

 I have been led to this conclusion by comparing Grapsus Pelii 

 with some typical specimens of Goniopsis cruentatus , which 

 we received from Mr. Alph. Milne Edwards and which 

 have been collected in Mexico. 



17. Grapsus dilatatus de Haan. 

 Mus. Lugd. in coll. Herklots. Symbolae Carcinol, p. 16. 



This species is identical with Metopograpsus pictus Alph. 

 Milne Edwards (Nouv. Arch, du Mus. t. IX, p. 289, pi. 

 Ill , fig. 2). The name given by de Haan must disappear from 

 science, never having been published. The specimen that 

 bore the name of Gr. dilatatus de H. , was collected at 

 Timor by Macklot. 



18. Grapsus simplex Herklots. 



Herklots , 1. c. pag. 9. Milne Edwards , Ann. Sc. Nat. 

 1853, p. 170. 



On account of the relation of the antennae to the orbits, 

 and of the shape of the external maxillipeds, this species 

 really belongs to the genus Grapsus M. Edw. 

 I*3^otes from the JLieyden Museum.
