species have been confused under the name of A. numidiciis and hope to be able 

 to give reasons for this opinion on a future occasion, 



Leptestheria sp.? 



A number of specimens of Leptestheria were found in collections made at 

 Amara, and these I believe represent a species hitherto undescribed. In shape 

 of shell they closely resemble L. ticinensis, CrivelU, but the arrangement of 

 spines on the post-abdomen is quite distinct and unlike that of any species known 

 to me. Unfortunately Dr. Daday has published in the Hungarian language 

 short diagnos3s of a number of new species oi Leptestheria (Math. Term. Ert. 

 1913), and, as these diagnoses are unaccompanied by figures, they are unintel- 

 ligible to me. Until Dr. Daday completes his monograph of the Conchostraca 

 in a language generally understood, the existence of this Hungarian synopsis 

 effectually limits the study of the group to those who can read this difficult 

 language. 



Baird (Proc. Zool. Soc. 1862, p. 148) has recorded the occurrence of L. dahala 

 censis, Rupp., together with Esther ia lofti, Baird, from pools by the river Tigris 

 near Bagdad. 



2. Cladocera. 



Daphnia lumholtzi, Sars. Taken in November and December 1917 in fire buckets 

 at Amara, and also in permanent marsh at Ezra's Tomb in February 1918. 

 In the former locality the adults had extremely short head spines, and the po- 

 sterior spine followed nearly the median line of the body, whereas in the young 

 the head spine was long and the posterior spine dorsally directed. Specimens 

 from Ezra's tomb were of typical form. The species is recorded from Australia, 

 East Africa, Egypt and Palestine. 



Daphnia magna, Strauss. In flood waters at Amara in January and March 

 1918. Though males were present no ephippial females were taken. Found 

 also at Qazvin in N. W. Persia. 



Daphnia pulex, De Geer. The obtusa form of this species was taken at Resht 

 in N. W. Persia in March 1919. 



Daphnia longispina. 0. F. M. 



Ezra's Tomb, Mesopotamia, and at Resht. N. W. Persia. 



Simocephalus exspinosus, Koch. 



Abundant at Amara in the moat of Fort Farm. 



Simocephalus vetulus. 0. F. M. 



Amara — in a disused well. Azize, Mesopotamia ; Enzeli and Resht, N. W. 

 Persia. 



Scapholeberis mucronata (0. F. M.) 



The hornless form of this species was taken in small numbers at Ezra's 

 Tomb (February 23rd, 1918 ). 



Scapholeberis aurita (Fischer). 



Common at Resht, N. W. Persia. 



Ceriodaphnia reticulata, Jur. 



Amara and Ezra's Tomb ; Resht and Enzeli. 



Moina rectirostris, Jur. 



In flood pools at Amara. Common. 



Moina dubia^ Richard. 



A few specimens of this species were found in a collection from the moat of 

 Fort Farm, Amara. 



In some respects these specimens are intermediate between M. dubia and 

 M. micrura, Kurz, since for example the postanal part of the postabdomen is 

 considerably shorter than that of typical M. dubia. On the other hand the com- 

 parative length of the antenna, the total length of the postabdomen as compared 

 with the body, the presence of transverse rows of ciUa on the postabdomen and
