468 THE VOYAGE OF H.M.S. CHALLENGEE. 



posterior margin. In all tlie specimens of botli sexes tliat I have examined the rostral 

 spine is laterally compressed and bent near its base, projecting horizontally forwards, and 

 there are but two spines upon the posterior margins of the basos joint of the sixth and 

 seventh pair of logs. It is probable, therefore, that a distinct species is figured by Buchholz 

 in the plate referred to." Halirages fulvocindus, Sars, is next mentioned, followed by 

 Gammams locusta, Linn.; Gammaracanthus loricahis, Sabine; Amathilla jjinr/uis, Kroyer. 

 Eusirus cuspidatus, Kroyer, is thus remarked upon, "The single example in the collection 

 is fully adult and bears ova. Lengtli 1 inch 7-J lines (-11 millims.). 



" The basos joint of the sixth and seventh pairs of legs is considerably narrowed to its distal 

 extremity. The second and third segments of the abdomen have the posterior margins 

 rounded and very finely serrated. This species lias been described at great length and 

 figured by Buchholz, /. c. ; but either the figure is carelessly executed as regards many details, 

 or it represents a very distinct species. The rostrum is represented as much longer than in 

 the specimens I have seen ; the coxa of the fourth pair of legs with its inferior margin 

 straight (not rounded as in the examples I have examined), the second and third segments 

 of the abdomen with the posterior margins strongly angulated, &c." 



Kotes are given on " TritrojJis aciilcafa," chiefly referring to the development of the ovigerous 

 lamellae in the females. 



jEgina spinosissima is given with references to JEgina spinosisshna, Stimpson, Gaprella spinifera, 

 Bell, IJEgina ecMnata, Boeck, Capirella sinnosissima, Spence Bate. "The largest 

 specimen, length nearly 2 inches 2 lines (54 millims.) is very robust, of a green colour, and 

 with but very few small spines and many indistinct very small tubercles ; the second pair 

 of legs has the hand armed upon its inferior margin with two very strong teeth, and a third 

 small tooth close to the distal extremity ; the finger is strong and very much curved ; the 

 first joint of the first pair of postabdominal appendages is short and much broader than 

 the second joint. 



"The smaller specimen, length a little over 11 lines (24 millims.), is of a whitish colour, purplish 

 brown at the bases of the spines, which are numerous, especially on the back. The hand of 

 the second pair of legs is nearly of the same form as in the preceding, but the finger is less 

 arcuate ; the basal joint of the second pair of legs not broader than the second joint. 



" In the specimens I have before me the teeth on the inferior margin of the palm of the second 

 pair are not only much larger than in JE. echinafa, but tlie palm itself is not tuberculated 

 as in that species, as figured by Boeck (/. c.) [pi. 38. fig. 6. 1876]. It is possible that the 

 two forms are distinct ; but the variation in the sjjines of the body and its limbs are known 

 to be very great in some species of the genus. 



" Probably the specimens referred by Eoss in Parry's 3rd and 4th Voj'ages to Caprella seolo- 

 yendroides, and which he describes as having ' a great number of small spines along the back,' 

 should be referred to uE. spinodssima. They were collected at Port Bowen and Low Island. 



" This species has been recorded from the coasts of Greenland, Spitzbergen, and Norway ; and if, 

 as I believe, the species of Stimpson is identical, from the Grand Manan at the entrance of 

 the Bay of Eundy."
