figures of the fifth pair are very little different from the ftgures published by me in 1902. The 

 small differences mentioned by Wolfenden are due to the preparation being examined from a 

 slightly different position. My paper was published some three years before the appearance of 

 Wolfenden's report on the Copepoda collected by J. Stanley Gakdiner around the Maldive Islands. 

 G. Smith (1909), p. 60, makes the following statement regarding the distribution of the 

 Candaciidae. "Some species, e. g. C. pectinata Brady, have a practically world-wide distribution, 

 "this species being recorded from the Shetlands and from the Phillipines". I am unable to tind 

 any record from the Phillipitie area except the one given by Brady in the report on the 

 'Challenger' Copepoda. The form illustrated in that report as Candace pectinata represents at 

 least four distinct species, none of which are identical vvith it. The illustratións on Plate XXX 

 in the 'Challenger' report represent Candacia èipinnata, C. curta, C varicans and C'. bradyi. 

 Candace pectinata Brady (1878), was shewn by Sars (1902) to be identical with Candace arniata 

 Boeck (1872), and the distribution is stated to be British Isles (Brady), Atlantic Ocean, between 

 Lat. n° and 50 D X. (Cleve), Mediterranean (Giesbrecht). Sars records it from the Coast of 

 Norway and from the East of Iceland. Esterly records and illustrates Candacia pectinata from 

 the Pacific in the vicinity of San Diego, California. Wheeler (1900) records it from Woods Hole. 



12. Candacia discaudata nov. sp. Plate XLVII, figs. 10 — 20. 



Female — length 1,94 mm. 



Seen from above, the body appears rather short and moderately robust. The frontal 

 margin is truncate. The distal ends of the last thoracic segment terminate in short spiniform 

 projections. Viewed from the side, the cephalic segment is considerably vaulted. The spiniform 

 projection of the last thoracic segment is directed ventrally (Plate XLVII, tig. 11). 



The combined length of the abdomen and furca is contained two and a half times in 

 the total length of the cep halothorax \ from the frontal margin to the base of the genital segment. 

 The genital segment is slightly asymmetrical when viewed from above. It is without lateral 

 projections. Lach side is furnished with one short setae. The length of the segment is nearly 

 equal to the combined length of the next two segments. The second segment is broadly 

 wedge-shapecl. lts length is equal to fully one-half of the length of the genital segment. The 

 anal segment is very short. It is distinctly asymmetrical. The furcal joints are twice as long as 

 broad (Plate XLVII, fig. 10). When viewed from the side, the distal end of the second segment 

 is seen to be considerably expanded. The distal end is much wider than the proximal end of 

 the next segment. The anal segment is very narrow. It is only equal to one-half of the width 

 of the distal end of the second segment (Plate XLVII, fig. 1 1). 



The antennules are composed of twenty-three joints, and reach to the middle of the 

 genital segment. 



The antennae. mandibles, maxillae and maxillipedes are similar to those of Candacia 

 norvegica (Boeck). The middle joint of the first maxillipedes is furnished with two spines. The 

 proximal spine is slightly longer and thicker than the distal one. The first proximal spine on 

 the third joint is much thicker than the second proximal spine (Plate XL\ II, fig. 13).
