SCHIZOPODS OF THE HAWAIIAN ISLANDS COLLECTED BY THE ALBATROSS 
IN 1902. 
By A. E. ORTMANN, 
Curator of Invertebrate Zoology , Carnegie Museum , Pittsburgh Pa. 
In the present collection there are represented 21 recognizable species, none of 
which are new, although one might be regarded as a new variety. Six species are 
already known from this region, 5 of which are distinctly pelagic forms, although the 
two species of Stylocheiron seem to prefer a certain depth. These 5 are: Euphansia 
bidentata, which was captured by the Albatross on a previous trip between San Fran- 
cisco and the Hawaiian Islands; Stylocheiron carinatum , which is known from the 
‘ ‘ North Pacific ” ( Challenger , without exact locality) ; Stylocheiron abbreviation , which 
was captured by the Challenger north of the Hawaiian Islands; Siriella thompsoni , 
which is known from the “North Pacific” ( Challenger ) and from between San Fran- 
cisco and the Hawaiian Islands ( Albatross ); and Siriella gracilis, which has been 
reported from the Northern Pacific by Streets and the Challenger, The sixth species 
previously known from this region is Boreomysis obtusata , which was found by the 
Challenger north of the Hawaiian Islands. This seems to be a deep-sea form. 
The other 15 species in this collection have not been found previously near the 
Hawaiian Islands. For some of them this new locality is not remarkable, since they 
have been found in other parts of the Pacific Ocean; but other cases are more or less 
interesting on account of the great distance of the localities from which they have 
been previously recorded. The discovery in the Pacific of the two pelagic forms, 
Euphausia pseudogibba and Stylocheiron longicorne , which were known hitherto only 
from the Atlantic Ocean, is in keeping with what is known of the distribution of 
related forms, and the same may be said of Nematodactylas boopis , which up to the 
present time was known only from Ireland. In two instances, however, Lophogaster 
and Anchialus , a very close examination of the material at hand was necessary to 
remove all doubt as to the actual identity of the species in question, since the known 
facts of distribution rather led to the expectation that the Hawaiian forms would 
prove to be distinct. 
Further detail concerning the geographical distribution of the single species 
will be given below at the proper places.
