diacal and intestinal regions are also a little hairy. The 

 anterior margin of the nieri of the chelipedes is provided with 

 two spines near the inner angle , a larger outer and a smaller 

 inner one, and with a strong spine at the external angle. 

 The anterior margin of the carpi of both chelipedes is 

 armed with three teeth , the posterior margin with four 

 teeth , becoming gradually smaller backwards. The outer 

 margin of both hands armed with six very small teeth. 

 The upper surface of the carpi and of that part of the 

 hands , which is situated outwards of the elevated ridge , 

 is covered with many curved rugose lines that are hairy 

 anteriorly; the remaining external part of the surface of 

 the hands closely covered with numerous similar but very 

 small and short rugose hairy lines. Our specimen is very 

 beautifully coloured, being of a light rose colour, and 

 marked with purplish red and white large spots , the penul- 

 timate and antepenultimate joints of the ambulatory legs 

 being violet-coloured with some few white cinctures. 



Alpheus edwardsii Aud. and Alpheus strenuus Dana.

 Berlin. Nov. 1878. pag. 830. 



Four specimens of the true A. edwardsii Aud. and three 

 of the form , regarded by Hilgendorf as belonging to the 

 A. strenuus Dana were collected at the same locality. The 

 former wholly agree with the figure of Savigny in the 

 «Description de I'Egypte, Taf. X, fig. 1", as regards the 

 relative length of the ambulatory legs of the second and 

 third pair and the relative proportions of the joints of the 

 carpus : the legs of the second pair being rather longer 

 than that of the third pair, and the second joint of the 

 carpus being longer than the fifth. Our four specimens 

 are all females, provided with eggs. 



Like Mr. Hilgendorf, I too cannot decide positively,
