I. 
branch of the last pleopods with only one booklet. Telson simple, flat, 
not armed. Epimera as in Amphithoe. Somewhat approaches Gaimnarus. 
A. longicorniSf sp. n., id. 1. c. p. 135, Red Sea. 
Cerapus tubularius (Say) again found, and accurately described by S. F. 
Smith. It differs from the known Fodocerinaj by having only three pairs 
of branchial lamellae, borne on the third, fourth, and fifth segments of 
the perion, and only three pairs of ovigerous lamellae, borne on the 
second, third, and fourth segments. The second and third pleopods are 
much smaller than the first, and their inner lamellae are rudimentary or 
very small. The second and third uropods are uniramous and nearly 
alike, the distal segment in each being short and terminating in a hooked 
point. It inhabits unattached portable tubes, and has large cement- 
glands in the bases of the first and second periopods. S. F. Smith, Tr.

Erichthonius difformis (M.-Edw.) = Cerapus rubricornis (Stimps.) =

Unciola irrorata (Say) = Glauconome leucopsis (Kroyer), abundant in

ISOPODA. 
R. Kossmann (Z. c. pp. 107-112) arranges the true Isopoda (Euisopoda, 
Heller, as opposed to Anisopoda) in the following manner, according to 
the observations of Schiodte : — 
Tribe 1. Asellidea. Mouth manducatory, caudal appendages 
styliform, body segmented. Fam. Asellidce and 
Oniscidoi.
