In 1852 Dana gave the foUowing descriptions of AnoJiylomern purpiiren and A. 

 tliyropoda. 



nA. purpurea: Four antennse about as long as body. Hands of third and fourth pairs siib- 

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

 and slender, moveable finger (without the claw) a little longer than the sui-face 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, 

 triangulär, 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 ajDex and 

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



y)A. thyropoda: Head transverse. Antennae (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, coxaj oblong, pentagonal, at apex but little wider 

 than preceding joint and entire, sides a little excavate; hand oblong triangulär, 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 lamells broad elliptical, some of them ciliate, entire.» 



The former species agrees in every respect with the specimens of x\nchylomera 

 Bl o SS e ville i in the collection of »Musée d'Histoire naturelle» in Paris; the latter is a 

 young female and agrees exactly with feuiale 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. anti^podeti, n. sp.; in all the quoted chara,cter- 

 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 body is thick and robust, Hyperia-\\k&. The integument is very thick and härd, 

 calcareous. The head and pertpon together are about as long as the pleon and urus 

 together. 



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

 coinmences 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.
