Fig. 1. Salmoneus trkristata sp. nov. a. Anterior region, dorsal aspect; b, small chela; c, second leg; d, third leg; 
e, telson and uropod. All drawn to same scale. 
Third legs with ischium half as long as 
merus, a little more than twice as long as 
broad; merus 5 times as long as broad, un- 
armed; carpus about two-thirds as long and 
less than half as broad as merus; propodus 
slightly shorter and thinner than carpus, 
armed with 4 feeble spines on superior margin 
and two similar spines on inferior, armed on 
distal inferior margin with a longer and heav- 
ier movable spine; dactylus half as long as 
propodus, slender, tapering and with a slight 
curve. 
Telson with anterior margin 2.5 breadth of 
posterior margin and length 4.5 times the 
posterior breadth; sides with uniform taper; 
terminal cleft one-ninth length of telson. Tip 
of telson armed with two pairs of spines, the 
inner as long as the tip is broad and the outer 
two-thirds the length of the inner. Cleft bear- 
ing two setae. Spines of dorsal surface of 
telson rather weak. 
DISCUSSION: The original name of this 
genus, Jousseatimea, has been changed by 
Holthius (1955:88) to Salmoneus, as the orig- 
inal name was preoccupied. 
With Coutiere’s entirely inadequate de- 
scription of his three species it is difficult, 
if not impossible, to be certain of any species. 
His original description of Jousseaumea lati- 
rostris (1896:382) was: 
"Les epines supra-oculaires sont tres peu 
marquees et le rostre tres large. L’une des 
pattes anterieures manque.” In 1897 (p. 234) 
he added that the large chela was like that of 
J. serratidigitus Coutiere, and in 1899 (p- 71, 
fig. 21) he supplied a dorsal view of the 
anterior carapace. 
As a consequence, until the three species 
described by Coutiere are redescribed ade- 
quately, every new species must be regarded 
as tentative. This species appears to be unique 
in the possession of the three crests on the 
anterior half of the carapace. S. cristata 
(Coutike) may have a somewhat similar 
medial crest, but the two lateral crests repre- 
sent the continuation of the lateral margins of 
the rostrum and do not arise from the corneal 
teeth as do the ones on this species. Other 
species have the rostral crest, like S. hilarula 
(de Man), but in them it does not extend as
