1926] Schmitt, Crustaceans Collected by the Congo Expedition 13 
The carpus of the first pair of chelipeds is usually just about twice as long as 
broad, varying from 1.9 in one case to 2.2 times as long as broad in another. In 
Bouvier’s figured var. decorsei, the carpus appears to be about 2.3 times as long as 
broad, while in Hilgendorf’s var. stuhlmanni this relation rises as high as 2.5. The 
movable finger seems to be most often five-ninths the length of the palm, but in 
many cases about equals the palm, or half the hand, in length. 
The carpus of the second pair of chelipeds is usually just about six times as lone 
as its greatest width, varying from 5 to 6.6 times as long as broad; the movable finger 
is predominantly 1.3 times the length of the palm, occasional spLchaons having the 
movable finger as much as 1.4 to 1.5 times as long; the carpus is from 1.2 to 1.3 
times the length of the hand. 
The dactyl of the third legs is about 5 times as long as wide, exclusive of the 
marginal spines, and is contained in the propodus about 3.5 times; the spines on 
the under or lower margin, including the apical or terminal one, number from 7 to 10 
(based on acount of twenty specimens); mostly there were 7 or 8 spines on the dactyl. 
The dactyl of the fifth legs is usually a little more than 6 times as long as broad, 
ranging from 5.8 times as long in one instance to nearly seven in another; it is con- 
tained in the propodus nearly 3 times, the propodus ranging from 2.7 to 3.1 times as 
long as the dactyl; in Bouvier’s figured var. decorset the propodus seems to be 2.4 
times as long as the dactyl. The number of movable spinules, not counting the 
immovable terminal one, varies from 51 to 80, the average of twenty specimens being 
65.6. Only in two instances did as many as three specimens have the same count, 
only the right leg of the pair being considered; these were three specimens each 
having 62 spinules on the dactyl of the fifth legs, and three with 73 spinules; two 
specimens had 51, and two 60. 
The uropodial spines range from 9 to 16 in number, the average of about twenty 
specimens being 12, though this particular count was not observed in any of the 
specimens. The greatest number of specimens showing the same count was five with 
10 spines, and five with 14 spines; three had 11 spines. 
The eggs do not appear to be quite as large as stated by Bouvier aad Hilgendorf, 
the former giving 1.1 X.6 mm. as the dimensions, the latter merely saying that they 
were over 1 mm. long. Those that I have measured range from .9 to .98 mm. long 
by from .55 to .57 mm. wide. 
Our specimens conform nicely with the key to the species of Carzdina 
elaborated by Bouvier! as the result of his detailed analysis of ‘Les 
Caridines des Seychelles’ obtained by J. Stanley Gardiner. In this key 
the usual number of uropodial spines in C. togoensis is given as 10 or 11, 
and the spinules on the dactyl of the fifth legs 42. As noted above, the 
number of uropodial spines varies from 9 to 16, with 10 and 14 being 
apparently the counts of most frequent occurrence, but, as to the spinules 
upon the dactyl of the fifth pair of legs, in none of the twenty specimens 
in which these were examined did the number fall as low as that given 
by Bouvier; the average number was about 65, with 62 and 73 most 
frequently occurring.
