species. The hands are from three and a half to four times as long as 

 their width across the palm, like those of N. lar. The eggs are larger 

 than those of N. lar or N. dentata, having a diameter of 

 about 1.8 mm. as against 1.2 in TV! dentata. 



Dimensions. Female bearing eggs, length 60 mm., 

 length of carapace 17.4 mm. Male, length 35.5 mm.,

The three foregoing species are not to be separated at a glance, but 

 the examination of hundreds of specimens of each shows that the differ-

NECTOCRANGON CALIFORNIENSIS Rathbun. 

 Nectocrangon californiensis RATHBUN, Proc. U. S. Nat. Mus., xxiv, 892, 1902. 

 Allied to N. ovifer. Represented only by small specimens which differ 

 from specimens of N. ovifer of equal size. The anterior margin outside 

 the orbital fissure is fur- 

 nished with two spines 

 close together, instead of 

 one in the allied species. 

 The eyes are smaller than in N. ovifer, 

 but have a prominent tubercle. The 

 spine of the antennal scale extends only 

 slightly beyond the blade. The hands
