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 

 6 about 1.8 mm. as against 1.2 m J\F. dentata. 



Dimensions. — Female bearing eggs, length 60 mm., 

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

Distribution.— Bering Sea, from 57O 39' 00" north latitude to Aleutian 

 Islands and Alaska Peninsula as far as Kadiak, 56-368 fathoms, at 26 

 stations of the Albatross. 



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- 

 ences here mentioned are constant.

 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 

 but have a prominent tubercle. The 

 spine of the antennal scale extends only 

 slighdy beyond the blade. The hands ^Y^%^^^io^'^(!^^!'''l^'iiox"^\l^^
