Hersiliodes Canuensis, nov. sp. PI. XXV, figs. 1 — 6. 



Form of the body cyclopoid, robust. The first thoracic segment 

 united with the head, the remainder free. Pleurae of the thoracic 

 segments well developed and prominent. Abdomen of three somites, 

 the first swollen, with the posterior angles produced into short spines, 

 with a small moveable spine exteriorly. Second abdominal somite 

 also produced posteriorly into short spines. Second and third 

 abdominal somites equal in length, the length of the first being 

 relatively to the second as 4 to 3. Furca very short, half as long 

 as the last somite, with three long hairs, and one shorter internally ; 

 two short spines on the outer edge. Antennae 6-jointed, the first, 

 second, fourth, fifth, and sixth joints subequal in length, the 

 third joint twice as long. Mandibles, maxillae, and maxillipedes 

 characteristic of the genus. Fifth pair of swimming feet flattened 

 as in H. Thompsoni, and provided with three flattened and serrated 

 spines, with a single seta internal to the innermost spine. 



Two specimens in No. 11. These are probably at a young stage, 

 as shown by the 6-jointed antennae, but they differ so markedly from 

 the described species of the genus, that I have felt justified in 

 ranking them as a separate species, and have named them after 

 M. Eugene Canu, whose researches have greatly improved our 

 knowledge of the family. In the form of the fifth pair of swimming 

 feet and in the internal maxillipedes S. Ganuensis closely resembles 

 H. Thompsoni, but differs from it in the details of the second 

 antennae, mandibles, and maxillae, and in the shape of the cephalo- 

 thorax and free thoracic and abdominal segments. 



In addition to the collections from the North Sea, Mr. Grenfell 

 sent me four bottles collected in the west of Scotland, and one from 

 Kinsale Bay.
