NEMERTEANS OF THE HAWAIIAN ISLANDS COLLECTED BY THE STEAMER 
ALBATROSS IN 1902.

Among the collections made by Prof. C. H. Gilbert and party with the U. S. 
Fish Commission steamer Albatross at the Hawaiian Islands in the summer of 1902 
are a number of well-preserved specimens of nemerteans. These specimens, how- 
ever, represent only three species, of which two are believed to have been unde- 
scribed hitherto. Microscopic study reveals a number of interesting anatomical 
peculiarities, which are detailed below. Two of the species belong to the genus 
Tseniosoma , which is abundantly represented in nearly all tropical and subtropical 
regions. The third belongs to the genus Dr&panopTiorus , but is unfortunately 
represented by the proboscis only, so that its specific identity is indeterminable. 
All the specimens were obtained by the dredge at depths of from 21 to 282 
fathoms. 
The fact that so few nemerteans were collected by the Albatross party must not 
be taken as an indication that more extended shore collecting would not yield a much 
larger number of species. Comparatively few miscellaneous collections of inverte- 
brates contain numerous species of this group, even from localities where such 
worms are abundant. So far as is known to the writer no nemerteans whatever 
have previously been recorded from the Hawaiian Islands or from the deep water in 
their vicinity. On this account the present collection, although very meager, 
possesses a certain interest. Its principal value, however, is due to the interesting 
anatomical peculiarities revealed in the new species it contains.

This genus is widely distributed in tropical and subtropical waters, and its presence at the 
(Hawaiian Islands was to have been expected. As has been stated elsewhere «, Stimpson’ s name for it
