Eriphia Icevimana. 



Eriphia Icevimana, Latr. (ined.), Guea'in, Icon. Or. pi. iii. fig. 1 ; M.- 

 Edwards, Hist. Nat. Cr. i. p. 427 (1834) ; Dana, Cr. U.S. Explor. 

 Exp. xiii. i. p. 249, pi. xiv. fig-. 7 (1852) ; Hilgendorf, Cr. in V. der 

 Decken's Iteise in Ost-Afrika, iii. p. 75 (1869); Monatsb. Ak. Berlin, 

 p. 797 (1878) ; A. M.-Edwards, Nouv. Arch. Mus. Hist. Nat. ix. 

 p. 255 (1873). 



Eriphia irapeziformis, Hess, Arch. f. Naturg. p. 135, pi. vi. fig 4 

 (1865). 



A male and female specimen of this species, presenting all 

 the characteristics of the typical form, are in the collection. 



I unite with E. Icevimana the Eriphia trapeziformis of 

 Hess, because there is nothing- in the description and figure 

 of the latter form to distinguish it specifically. 



Eriphia Icevimana, var. Smithii. 



Eriphia Smithii, M'Leay, Annulosa, in Smith's Illustr. Zool. S. Africa, 

 p. 60 (1838) ; Krauss, Siidl. Afrik. Crust, p. 36, pi. ii. fig. 3 (1843). 



Eriphia Fordii, M'Leay, I. c. p. 60 (1838). 



Eriphia Icevimana, var. Smithii, Hilgendorf, Monatsb. Akad. Berlin, 

 p. 797 (1878). 



New Guinea (an adult male). 



The tuberculation of the chelipedes is subject to much 

 variation according to Hilgendorf (I.e.), whom I follow in 

 considering E. Smithii merely a variety of Icevimana, the 

 series in the Museum collection not being large enough to 

 show whether the differences between the two forms are 

 constant. 



I may note, however, that in two specimens (young male 

 and adult female) from Natal, which I regard as typical con- 

 ditions of E. Smithii, the surface of the larger chela is 

 strongly granulated between the tubercles, which are rounded 

 and not crowded, and occupy only the upper part of the outer 

 surface ; and the tubercles of the smaller hand are crowded 

 and acute, and cover the whole of the outer surface of the 

 hand. In the specimens from New Guinea, also a male from 

 Zanzibar, a female from Dukhun (Deccan?), India, and in a 

 young female received from the Paris Museum under the 

 name of E. rugosa, M.-Edwards *, the surface of the larger 

 hand, between the tubercles (which are very faintly marked 

 or obsolete), is smooth, and the tubercles of the smaller hand 

 are less numerous and acute, and show a tendency to disposi- 

 tion in longitudinal series. 



Of this form I have also seen a fine male from Pulo Sambu, 

 Singapore, in a collection made by Surgeon-Major Samuel 



* I do not know that this name has ever been published.
