Fig. 4. Synalpheus coutierei Banner, a, b , Anterior body region; c, large cheliped; d , small cheliped; e, second leg; 
/, third leg; g, third leg, dactylus; h, telson. 
locality: One female, collected at station 
E-2-343. 
discussion: This specimen agrees well with 
Coutiere’s description and figures of his type, 
the sole specimen reported until now, except 
for several minor details. The setae on the 
small chela, shown as a definite tuft and de- 
scribed as "une brosse de soies seriees . . . 
moins seriees et moins abondantes que dans 
le groupe laevimanus . . appear to be less 
abundant in the distal tuft in this specimen 
and are also found proximal to the tuft in a 
row leading towards the articulation. The in- 
ferior distal margin of the merus of the third 
leg bear a feeble movable spine, instead of 
being unarmed as depicted by Coutiere. Fi- 
nally, the posterior lateral angles of the telson 
are produced into slender acute teeth almost 
as long as the lateral distal spines instead of 
being broader and relatively shorter as shown 
by Coutiere. However, the proportions of the 
small chela and third legs are almost exactly 
the same as in the type. 
The specimen described by Coutiere lacked 
the large chela, which is intact but slightly 
distorted in this specimen. It is of typical form 
for the genus, with the fingers occupying the 
distal 0.3 of the chela, and the height being 
about 0.4 of the total length (this proportion 
may not be accurate because of the condition 
of the appendage). The merus is 0.5 as long 
as the chela and 2.5 times as long as broad. 
The merus and the dactylar articulation are 
unarmed.
