158 BRITISH COPEPODA. 
It is, indeed, difficult to say with any degree of cer- 
tainty what species Goodsir had in view, his written 
and engraved descriptions being altogether inadequate. 
On this account I venture to propose a new specific 
name, Goodsiri, for the form here referred to. 
Genus 30. Pautipium, Philipp (1839). 
(Alteutha, Baird, 1845. Carillus, Goodsir; Sterope, Goodsir (in part), 
1845.) 
Body depressed, incised between the segments, ovate 
or subovate, abdomen not distinctly separate from the 
cephalothorax; integument very strong and thick; 
caudal segments and setze short. Anterior antenne 
shorter than the first body-segment, 9-jointed, slender 
and tapered in the female, in the male knotted and 
clawed at the apex ; posterior antenne 4-jointed, a small 
2-jointed secondary branch attached to the apex of the 
second joint. Mandibles minute, basal joint of the 
palp expanded distally, and bearing two 1-jointed 
branches, the innermost of which is the longest; each 
branch as well as the base bears three sete, and the 
longer branch has also a small lateral uni-setiferous 
digit. Maxille very small; palp much larger than the 
masticatory portion, composed of a basal joint and 
three setiferous segments, the middle being the largest, 
clawed at the apex, and provided with a short lateral 
setiferous process. First pair of foot-jaws laterally
