prolongation of the 4*^^ joint, this process itself reaching much beyond ^the 

 5*^ joint, its lateral margin fringed with 12 plumose setae, the apical 2 much 

 the longest. Peraeopod 1, 2^^ joint much shorter than rest of limb, G''' shorter 

 than 5*^, little longer than 7^^. Peraeopod 2, terminal joint nearly as long 

 as 3 preceding joints combined. Peduncle of uropods longer than the subequal 

 rami, its medial margin in adult d closely fringed with spines, as is also 

 the i"* joint of the endopod, which is more than twice as long as the narrow

2^^ joint, that carrying distally 4 spines and 2 long setae; in younger speci- 

 mens the relations are different, the 1^* joint not nearly twice as long as 

 the 2°*i, and in 2. macrobrachium the exopod much shorter than the endopod.

d. Pseudorosti-al lobes obliquely subtruncate, meeting a little in front 

 of the semicircular eyelobe. Carapace smooth; 3^ and 4*^ pedigerous seg- 

 ments with articulating arrangement sti'ongly developed; 5**^ segment of pleon 

 distallv narrowed, telsonic segment with dorsal depression. Eye obscure. 

 Antenna 1, 3^ joint a little longer than 2°^ Maxilliped 1 with the branchial 

 leaflets numerous, closely contiguous. Maxilliped 2, 2^^ j^int gradually widening 

 and then rather abruptly narrowing to the apex. Maxilliped 3, distal process 

 of 2^^ joint not nearly reaching apex of distal process of 4*^ joint. 5^^ joint 

 unusually widened distally on the medial side, as in Heterocnma sarsi (p. 48). 

 Peraeopod 1, 2^^ joint narrowed distally, nearly as long as rest of limb and 

 subequal to peraeopod 2, in which the 2"*^ joint is distally widened with
