48 BRITISH COPEPODA. 



M. Boeck states that the inner branch of the first 

 pair of feet consists of two joints ; but after careful 

 examination I have not been able to see any separa- 

 tion into two segments. It is quite possible, however, 

 that this character may vary somewhat in different 

 individuals, as it certainly does in the case of Temora 

 longicornis. It seems not unlikely that in very old 

 specimens the separation of the segments may become 

 more distinct, but in this case the individuals examined 

 appeared to be fully grown and matured. 



Genus 4. CANDACE, Dana (1846). 



(DANA, American Journal of Science, ser. 2, 1846.) 

 (Ijionyx, Kroyer, 1849.) 



Anterior antennae 23- or 24-jointed, that of the male 

 on the right side geniculated, and having the median 

 joints only slightly swollen. Posterior antennas stout ; 

 the secondary branch having no median joints. 

 Rostrum rounded. Mandibles twisted, narrow, ending 

 in two stout teeth, the palp very much expanded. 

 Maxillae bearing a long styliform process, masticatory 

 portion sub triangular. First pair of foot jaws very 

 strong, bearing long uncinate setae, second pair 

 slender and small. Fifth foot in the female composed 

 of one triarticulate branch on each side, those of the 

 male dissimilar, the right prehensile. Abdomen com- 

 posed in the female of three, in the male of five 

 segments.
