380 DR. W, M. TATTERSALL ON THE STOMATOPODA AND 



is only one spine on the outer uropod at the suture. These small differences 

 may he due to immaturity, as the specimens are in otherwise close agreement 

 with A. buceplialoides. 



Distribution,. This species is new to the fauna of the Red Sea and is other- 

 wise only known from Nobili's record from the Persian Gulf.

 A. consobrinus, De Man, 1911 b, p. 360, pi. 16. fig'. 75. 



Localities. Station V. A, 1 $ , 1 ? , 14 mm. Station V. D, 1 <J , 9 mm. 

 Station V. E, 2 ? , 14 mm. Station VII. 0, 1 J , 1 ? , 10 mm. Station 

 IX. A, 1 J, 2 ?, 9 mm. 



Remarks. This species is very closely allied to A. buceplialus, Coutiere, but 

 differs in having the fingers of the small chela of the male expanded and 

 hairy. The differences between the two species do not seem to me to be 

 clearly established, but by reason of the above character I refer my 

 specimens to De Man's species. 



Distribution. New to the fauna of the Red Sea ; otherwise only known 

 from the waters round the Dutch East Indies.

Remarks. This specimen agrees very well with the descriptions of 

 A. insignis except that the lateral lobes of the rostrum are not setiferous. 



Distribution. Recorded previously from the Red Sea by Heller, Paulson, 

 De Man, Xobili, and Coutiere ; otherwise widely distributed in the Indo-
