eoudees; leur pedoncule compose de trois articles et la tige terminale de plus de cinquante. 

 Les pattes de la premiere paire beaucoup plus courtes que les secondes; Tangle iuferieur de la 

 main de celles de la cinquieme paire est prolonge en pointe, mais ne depasse point les dents 

 dont le bord posterieur de cet article est arme; enfin l'ongle qui termine la griffe mobile de ces 

 memes pattes, long et grele». 



In 1852 Dana gave the following descriptions of Anchylomera purpurea and A. 

 thyropoda. 



»A. purpurea: Four antennas about as long as body. Hands of tbird and fourtb pairs sub- 

 triangular, third with an acute point as an immoveable finger, fourth with this finger elongate 

 and slender, moveable finger (without the claw) a little longer than the surface on which it closes, 

 claw rather long. Feet of fifth pair very large, coxa oblong, pentagonal, with sides a little con- 

 cave, narrowed towards the apex, where it is but little wider than next joint, hand oblong, 

 triangular, straight and dentate within, finger (claw excluded) longer than the hand, claw rather 

 long. Sixth pair of feet long, fourth joint rather long subcylindrical, coxa acute at apex and 

 posterior basal angle rounded. Seventh pair weak, coxa a little longer than the following part.» 



»A. thyropoda: Head transverse. Antenna? (probably not adult) very short, without a fla- 

 gellum. Second pair of feet longer than first, subulate. Hand of third and fourth pairs trian- 

 gulate, inner margin and palm very finely serrulate or spinulous, finger (claw excluded) not 

 longer than palm. Fifth pair of feet very large, coxa; oblong, pentagonal, at apex but little wider 

 than preceding joint and entire, sides a little excavate; hand oblong triangular, palm dentate, 

 external tooth little the largest; finger, excluding claw, much shorter than palm. Sixth feet of 

 moderate size, second, third, and fourth joints short, subequal; seventh pair obsolete, excepting 

 coxa. Caudal lamella; broad elliptical, some of them ciliate, entire. » 



The former species agrees in every respect with the specimens of Anchylomera 

 Blossevillei in the collection of »Musee d'Histoire naturelle» in Paris; the latter is a 

 young female and agrees exactly with female specimens taken together with typical spe- 

 cimens of A. Blossevillei by myself during the expedition of His Swed. Majesty's Corvette 

 Balder in 1882; such being the case, I have, without hesitation, placed both species as syn- 

 onyms for A. Blossevillei. 



In 1862 Spence Bate described A. antipodes, n. sp.; in all the quoted character- 

 istics it agrees with the type species, so that there is no doubt about its identity with 

 A. Blossevillei. 



In 1888 Stebbing gave an exhaustive description of A. Blossevillei, recording 

 all the other species as synonyms for it. 



The male. 



PI. XVII, tig. 1, 2, 4, 6—18, 20, and 22. 



The body is thick and robust, Hyperia-\ike. The integument is very thick and hard, 

 calcareous. The head and perceon together are about as long as the pleon and urns 

 together. 



The head is large and deep, nearly twice as deep as long. The antennal groove 

 commences just above the middle of the front side, and is tolerably deep. 



The eyes are divided into an upper and a lower portion on each side of the head; 

 the lower portion is much the larger. At the crown of the head the eyes are separated 

 by a tolerably broad space.
