List op Species. 



I. MALACOSTRACA* 



Sesarma boulengeri. Caiman. (Ann. Mag. Nat. Hist. (9) V. 1920). 



Fao, Persian Gulf, in brackish water. 



The specimens from which Dr. Caiman's description was taken were collected 

 at Basra, in fresh water. 

 Potamon fluviatile var. ibericum, Marschall de Bieberstein. 



Tula Rud (S. W. Caspian), Qazvin and Kermanshah (N. W. Persia). 

 Potamon fluviatile var ? Qalat Saleh, R. Tigris. 



II. ENTOMOSTRACA. 



1 . Phyllopoda. 



Artcmia salina var. arietina, Fischer — Daday. 



A large number of specimens of Artemia "s^ere taken in saline pools in the 

 neighbourhood of Amara, but among them no males were found. The number 

 of setae on the furcal rami is very variable, ranging between 12 and 2, the aver- 

 age being 8 on each ramus. 



Apus asiaticus nom. nov. 



Apus granarius, Sars. Ann. Mus. St. Petersb. VI. 1901, p. 4. 



I have received from Dr. Annandale and from Dr. W. T. Caiman specimens 

 of Apus taken at Bagdad, and, though Dr. Annandale's specimens are small 

 and immature, I have no doubt that all belong to the same species. The adults 

 agree very closely with the species from Central Asia described by Prof. Sars 

 under the name of A. granarius, Lucas, but I am not satisfied that that name 

 is correctly appKed. M. Simon's description (Ann. Soc. Entom. France VI. 1886, 

 p. 446) is not very full and no figures are given, but he states that the flagellum 

 of the first leg exceeds the length of the dorsal shield, which is far from being the 

 case in Prof. Sars' species and my own. There are other differences also with 

 regard to the length of the furcal rami, which M. Simon also states are " prope 

 basin obtuse dentati baud setosi ", and the denticles on the sulcus of the dorsal 



^ I am indebted to Dr. W. T. Caiman for the identification of these Crabs.
