curved tooth. In the absence of dorsal teeth and of serra- 

 tions on the third pleon segment this specimen agrees with 

 /". r>v/.v.v/. A second specimen, about 15 mm. long, a female 

 bearing eggs, is similar in general appearance and in the 

 appendages, bul lias the posterior margin of the third pleon 

 "-"ument with numerous dentations as drawn by Stebbing 

 for E. ponipfii, there is a very slight indication of pleon 

 segments one and two being produced into dorsal teeth, but 

 no sign of a tooth on pleon segment four, the presence of 

 which in the previous specimen seems to be exceptional. 

 The third specimen, also a female with eggs, about 13 mm. 

 lonu 1 , has the first and second pleon segments very slightly 

 produced, and is similar to the second in practically all 

 other characters, but the third pleon segment has more 

 numerous serrations, these being nearly as numerous as 

 shown by Stebbinir for E. caesaris. The fourth speeimeri. 

 about 12 mm. long, also a female, is similar to the second 

 and third but has only about six or seven serrations on the 

 third pleon segment, the rest of the margin being slightly 

 uneven. 



Oft Kingston, South Australia, two specimens (Reg. No. 

 E. 4862") were collected, each about 15 mm. long, and havina 1 

 the serrations on the third pleon segment intermediate in 

 character between those shown for E. caesaris and 

 E. ponipeii by Stebbing. One of them also showed very 

 slight dorsal production of pleon segments one and two. 



Certainly all the "species" mentioned above must, in my 

 opinion, be placed in one genus, and the name Bovallia 

 appears to have priority over Eusiroides.
