Pheretima Schnarde (Horst.) Mich. 
In formalin pale buff, with a purplish or chocolate-brown clitellus. 
In life, often dark brownish red or sometimes greenish or olivaceous. 
In formalin the segments are mostly carinate or angular, with long 
rows of hooks. It is a very lively species, and when disturbed 
wriggles about very actively, much like a salamander, and when 
caught often breaks itself into two or more pieces. New to Ber- 
muda; known from Barbadoes. 
Common under stones at the old Walsingham house. 
Pheretima Rodericensis (Grubé) Mich.= Pericheta Dyeri Bedd. 
A rather large species, 4-6 inches long. Color in formalin light 
yellowish brown ; segments anteriorly and posteriorly with a promi- 
nent angular median carina, bearing long rows of hooks. Widely 
diffused in warm climates ; West Indies. Active like the preceding. 
Onychocheta Windlei Bedd. = Diacheta Windlei Bedd. Under 
stones, not common. 
In addition to the above, Beddard has described, 1894, from this 
locality Pheretima Bermudensis Bedd., as Pericheeta, which is widely 
diffused in the warmer parts of both hemispheres. Also, 1891, Pon- 
todrillus Bermudensis (?=P. arence Mich., t. Moore).

b6.—Land Nemerteans. 
A species of terrestrial nemertean ( Tetrastemma agricola W.Suhm) 
was discovered in Bermuda by the Challenger Expedition.* We 
found it common under stones and logs, near Hungry Bay, not 
only close to the shore, but also on the hillsides where the soil was 
rather dry. It is said to live also in the holes of land crabs. Full- 
grown individuals are sometimes six inches long, in full extension, 
and very slender. It has four small but very distinct black eyes in 
a quadrangle. The color above is dusky brown, grayish, or smoky 
brown, paler below. See Plate C; figure 4. 
Although it is known only from Bermuda, its habits and localized 
distribution are like those of a recently introduced species. It is 
associated with foreign species of earthworms and isopods ; still it 
may, perhaps, prove to be endemic. We brought back living speci- 
mens in bottles of damp earth and mould without difficulty.
