breadth of the Djeddah specimen is 133 millim. The individual 
from Sullivan Island belongs to the variety melanodactyla, the 
fingers being dark-coloured with white tips. The right leg is 
largest. The frontal margin is armed between the dentiform 
internal orbital angles, on each side of the median furrow, with 
five small acute teeth: the first, third, and fifth are of equal size, 
the second and fourth a little smaller; the first or median teeth 
are a little more prominent than the others. 
Cymo Andreossyi, with the variety melanodactyla, 1s distributed 
throughout the Red Sea, the Indian Ocean, the Malayan archi- 
pelago, as far as the Fiji and Samoa Islands.

Three rather young specimens were collected at King Island. 
I am indebted to Dr. F. Meinert of Copenhagen for an ex- 
cellent photograph of the typical specimen of Fabricius’s Cancer 
Rumphii, collected by Daldorff on the coast of Tranquebar. 
After having compared these specimens with that figure, I was 
led to the conclusion that they belong to Menippe Rumphii, Fabr. 
I then sent one of them to Dr. Hilgendorf, who informed me 
that it was also identical with Herbst’s Cancer Rumphit. As 
had already been proved in 1872 by Prof. von Martens, I am also 
inclined to regard Milne-Edwards’s Pseudocarcinus Belangeri as 
identical with the true Menippe Rumphi, Fabr., whereas Pseudo- 
carcinus Rumphii, M.-Edw., is doubtless a different species. 
I have before me an adult male specimen of Menippe Rumphii, 
Fabr., collected on the coast of Atjeh, and I may now add 
the following particulars to the existing descriptions of this 
species. 
Menippe Rumphii, Fabr., really belongs to the genus Menippe, 
because the peduncle of the external antenne occupies the
