outer orbital angles should be 7*5 mm., the length 6 mm., but the 

 abdomen is apparently included, for, according to the figure, the 

 length appears to be 5 mm., so that in this species the carapace 

 is broader in proportion to its length, being just once and a half as 

 broad as long. The frontal lobes are seven in number, the front 

 is broader and the external m.axillipeds are also different. 



Pachygrapsus longipes, Rathb. {Proc. National Museum, xvi, 

 i8g3, p. 247, and Bull. U. S. Fish Commission for 1903, Wash., 1906, 

 p. 840, pi. viii, fig. 7), from Honolulu, appears to resemble very 

 much Pach. planifrons , de.Man, from the Bay of Batavia (Archiv. 

 f. Nalurg., bd. 53, 1888, p. 368, pi. xvi, fig. 2), but it is quite 

 remarkable that neither Miss Rathbun nor Dr. Borradaile make 

 mention of this species.^ Unfortunately Miss Rathbun does not 

 say whether, in Pach. longipes, the front is deflexed or not, but in 

 the figure, published in 1906, the front resembles that of Pach. 

 planifrons. According to this figure the propodal joints of the 

 ambulatory legs should be slenderer than those of our species from 

 Port Canning, so, e.g., the propodites of the penultimate pair appear, 

 ill that figure, four times as long as broad ; in the larger specimen 

 of Pach. propinquus , however, these joints are three times as long as 

 broad, viz., 5 mm. long (measured along their posterior margin) and 

 I "6 mm. broad. I therefore suppose this Hawaiian form to be 

 distinct from the species of the brackish pools at Port Canning. 

 The slate-coloured upper surface of the carapace, and the red-brown 

 legs are mottled with small dark spots. Measurements of the two 

 specimens in millimetres —

Port Canning, brackish water pools, January 28 — 30, 1906, 



collected by Dr. N. Annandale, four males, two females (Reg. 



No. - — - ; Nov. 12, 1906, nine males, three females). 



Backergunge, seven males, nine females, collected by H. E. 



Stapleton (Reg. No. ^^). 



Dhappa, near Calcutta, slightly brackish water, twent5^-eight 

 males, two females. 



All the specimens are young, the largest being a female from 



I I wish to call attention to the fact that iu vol. xxv of the Zoological Record 

 for 1888 my paper on the Crustacea collected by Dr. Brock {Archiv. f. Naturg., 

 bd. 53, 1888) was mentioned in the List of Publications but not in the Systematic Part. 

 The Zoological Record should not have been entrusted to such regardless authors.
