56 CFIUSTACEANS OF THE 



Myomenippe Hilgd. 



Myomenippe apparently contains only two species : 

 1° Myomenippe Hardivickii Gray. 

 2° » Fornasinii Bianc. 



Menippe Bumphii Pabr. is identical with Menippe Belan- 

 geri H. M. E., but Menippe Bumphii H. M. E. is au 

 American species, inhabiting the coast of Brazil (A. 

 Milue Edwards, Etudes sur les Xiphosures et les Crustacés 

 de la Region Mexicaine, p. 263, PI. 48, fig. 4). 



Me7iippe granulosa Strahl (1861) is, according to von 

 Martens (1872), identical with Menippe Panope Herbst. 



There can be no doubt that Myomenippe Hardioickii 

 Gray, the type of which is from the Indian Ocean, and 

 Myom. duplicidens Hilgd. from South Celebes are one and 

 the same species (confer: Miers, Annals and Magazine 

 Nat. History, Ser. 5, Vol. 5, 1880, p. 233). As I have 

 previously shown (in : The Journal of the Linueau Society, 

 Vol. XXII, 1888, p. 40), Myom. duplicidens Hilgd. is also 

 identical with Myom. granulosa A. M. E. (1867). 



The second species of Myomenippe., found in the Indo- 

 pacific Seas, is Myom. Fornasinii Bianc, described below. 



Pelaeus armatus Eyd. & Soul. (Voyage de la Bonite) 

 belongs, according to Dana, to the genus Menippe and I 

 am of the same opinion. This species, that occurs at the 

 Sandwich Islands, differs by several striking characters 

 from the four other species of this genus. The front is 

 quadridentate, the first and the second an tero -lateral tooth 

 are lobate and incised, the third is acuminate anteriorly, 

 the fourth is spiniform. 



Menippe guadridens de Haan and 31en. af finis de Haan, 

 both from the Moluccas, are nomina uuda (Fauna Japo- 

 nica, p. 21). 



Menippe parvula de Haan , Cape of Good Hope, is a 

 true Actaea (de Man, 1. c. p. 27).
