wise known from the original record of: Miers from Goree Island, Sene-

Edwardsi group. 

 Alpheus audottnii, Coutiere, 1905, p. 911, pi. 87. fig. 52. 

 A. auduuinii, De Man, 1911 b, p. 414, pi. 23. fig, 100. 



Locality. Station V. E, 1 J , 21 mm., 1 ? , 19 mm. 



Distribution. This species has hitherto been confused with A. ediaardsii, 

 Audouin, so that the previous records for the Red Sea are not easy to 

 determine. It has, however, been certainly recorded by Nobili and Coutiere 

 from this area.

Localities. Station I. A, one specimen, 28 mm. Station V. E, two speci- 

 mens, 17 and 24 mm. Station VII. C, one specimen, 22 mm. 



Distribution. Previously recorded from the Red Sea by De Man, Nobili, 

 and Coutiere ; a widely distributed Indo-Pacific species.

Localities. Station Y.A, 2 <J , 12 and 13 mm., 5 $, 9-14 mm. Station 

 V.-B, 14 specimens. Station V. C, 2 $, 8 and 10 mm. Station V. E, 2 <? , 

 13 and 14 mm., 2 oyig. ? , 12 and 14 mm. Station VII. C, 2 $ , 12 and

 ovigerous female Alpheids, from among coral in one fathom of water at 

 Mersa Ar-rakiya, which were too much damaged to identify with certainty.
