A, Malmgreni^ the last joint of the peduncle heing less deve- 

 loped than in Goes's figure of that species. The penultimate 

 joints or palms of the first and second legs in A. pulchra are 

 regularly ovate, without indications of teeth on the inferior 

 margins as in Goes's representation of A. Malmgreni. The 

 coxal joints of the legs (]3articularly of the fourth and sixth 

 pairs) appear to be more developed. As in A. Malmgreni, the 

 seventh thoracic legs are greatly elongated. The uropoda 

 and terminal segment do not present any very marked dis- 

 tinctive characters. Length of the largest specimen to tip of 

 rostrum about 1 inch 5 lines. 



Three females were collected. 



The absence of spines at the postero-lateral angles of the 

 posterior thoracic and postabdominal segments would suffi- 

 ciently characterize this species, independently of the other dis- 

 tinctions enumerated in the above diagnosis. 



The outer maxillipedes are very similar to those of A. 

 Mahngreni as figured by Goes. The outer lamina reaches 

 very nearly to the middle of the dilated antepenultimate joint 

 of the palpus. 



Halirages falvocinctus ( Sars) . 



A good series of specimens (females) are in the collection, 

 which agree very well with Goes's figure of the species, and 

 with the specimens collected by the late British Arctic expe- 

 dition. 



AmatMllopsis affinis, sp. n. 

 (PI. VII. figs. 3-5.) 



The head is produced anteriorly into a short, con vex, subacute 

 rostrum, which does not reach nearly to the distal end of the first 

 joint of the superior antennae, and has a small antero-lateral lobe 

 on each side between the sujierior and inferior antennge. As 

 in AmathiUopsis spinigera^ Heller, the dorsal surface of each 

 of the thoracic segments and of the first three postabdominal 

 segments bears a long acute dorsal lobe or spine ; and, as in 

 that species, the spines become successively longer, the last 

 excepted, which is very small. As in A. spinigera^ the lateral 

 margins of the first three postabdominal segments are sinu- 

 ated and terminate in a spine at their postero-lateral angles. 

 The terminal segment is less dilated at its distal end, which 

 is very slightly emarginate. The superior antenna3 terminate 

 in very long and slender flagella, and are nearly twice as long 

 as the inferior antennae ; the terminal joint of the peduncle 

 is relatively shorter than in A. spinigera, and the accessory 

 flagellum so minute as to be undistinguishable except under
