Excerpt from On the Crustacea Isopoda of the 'Lightning,' 'Porcupine,' and 'Valorous' Expeditions
Animal narrow, subdepressed, or subcylindrical, but never compressed.
Head united with the first or, more rarely, with the first and second segments Of the peraeon, so as to form a short carapace, the surface of which is Often areolated with lines of depression. The following segments of the peraeon are always distinct, and are Often separated by deep constrictions.
The pleon is composed of six segments, the first five of which are usually distinct (but in some cases coalesced into a single segment), and furnished with pleopods, which consist of a basal joint and two unjointed branches (but in those cases where the segments are coalesced, and sometimes otherwise, the pleopods are undeveloped). The last segment is formed by the union Of the two last segments of the pleon, and is much larger than the preceding, and carries the uropods.
The eyes, when present, are situated on triangular lobes, at the anterior angles Of the carapace.
The upper antennae are furnished with either one or two flagella.
