1926) Schnutt, Crustaceans Collected by the Congo Expedition 20 
Four specimens (two ovigerous) of this species from St. Paul de 
Loanda, September 22, 1915. ‘Was caught hiding among bunches of 
ascidians and sponges in the bay of St. Paul de Loanda.”’ (H. L.)! 
These specimens represent one of the forms of this variable species. 
The mandibular palp is unquestionably two-jointed; the coalesced 
portion of the shorter ramus of the outer antennular flagellum is about 
two-thirds the length of the free portion. The fingers of the second legs, 
however, are from two-thirds to three-fourths the length of the palm; 
the carpus is subequal to or a little longer than the merus, and about 
three-fourths, or a little more, the length of the chela. 
The rostrum of all four specimens had uniformly ten teeth above 
and three below, except one specimen lacking the rostral tip which had 
nine above. Three teeth are on the carapace in all but one of the speci- 
mens; in this two were behind the orbit and the third just over the 
orbital margin. The anterior dorsal tooth is subapical, close behind the 
tip.

De Man (loc. cit.) has anticipated me in announcing the identity of 
Leander [Palzeemon] edwardsii of Balss with the species described by Thall- 
witz. He compares it with Leander [Palemon] longirostris (H. Milne 
Edwards) saying that “L. [Palemon| maculatus may be distinguished 
from the typical L. [Palemon|] longirostris (H. M. Edw.) especially by the 
shape of the rostrum, by the shorter ramus of the outer antennular
