The Actoniscus ellipticus Harger is otherwise known only from 
New England. 
The common bluish gray Ligia Baudiniana M. Edw., which runs 
very rapidly over the rocks, is found on all the sea-side ledges and 
cliffs and hides in their crevices. It is widely distributed in the 
West Indies and Tropical America. Figure 233. 
Ligia oceanica, figure 234, probably also occurs, but we did not 
obtain it. Its distribution is world-wide in warm climates.

Dr. Fr. Dahl (Plankton Exped., i, pt. 1, p. 111, pl. iii, figs. 2, 4, 5, 
7, 8, 10, 13, 1892) recorded an additional species of terrestrial isopods, 
(Philoscia Bermudensis, sp. nov.) See figures 235, a—e. 
40.—Introduction of Earthworms ; Land Nemerteans, ete. 
a.—Earthworms. ( Oligocheta.) 
Whether any earthworms were native to Bermuda is uncertain, 
though at least one species is not yet known from any other 
locality. The greater part of the common species have undoubtedly 
been introduced with the earth around growing plants. Several are 
well known European species, introduced also into North America. 
The following species have been identified, from our collections, by 
Dr. J. Percy Moore, who has recently published a list of the species, 
with descriptions. (See Proc. Philad. Acad., liv, pp. 80-84, 2 cuts, 
April, 1902.)
