1594 CRUSTACEA. 



although hardly differing from Alpheus. The anterior hands are 

 stout and very nearly equal. 

 Page 535. — Typton, Costa (loc. cit.) is also near Anchistia in habit. But the 

 author states that there is no basal scale to the outer antennae, and 

 in this respect it is abnormal among the Caridea. 



" 593. — Add under Hymenocera pieta, references to Latreille, Regne Anim., 

 iv. 95, and Edwards, ii. 348. 



" 600. — Cerataspis of Gray (Cryptopus of Latreille) has not been inserted 

 among the Mysidea, as Edwards has observed that there are regular 

 branchiae as in the Caridea, and remarks that the animal is probably 

 the larve of some Penaeidean ; see Gray's Spicilegia Zoolog., p. 8, 

 PI. 6, f. 5, and Edwards, Crust., ii. 439, and Regne An. Illustr., 

 PL 54 bis, f. 4, and note to this plate. If a distinct genus of the 

 Penaeidea, as is altogether probable, it should be arranged with the 

 Sergestidae. 



" 600. — Solenocera is a name given by Lucas, in his work on Algiers, to a 

 genus of Penaeidae. 



" 615. — Phyllamphion of Reinhardt (Vid. Med. af den nat. Forening, 1849, 

 ii.) is a genus between Phyllosoma and Amphion. 



" 622. — Under Pseudosquilla sty lifer a, add reference, Squilla stylifera, 

 Lamk., Hist, des An. sans Vert., v. 189; Edw., Crust., ii. 526, &c. 



" 697. — Crlyptonotus. This genus is instituted by Dr. Eights for a gigantic 

 Idotaea from the South Shetlands, related to I. entomon, which it 

 would also include. The species is called 6r, antarctica. Trans. 

 Albany Institute, ii. 331, 1838-1852. 



" 697. — The genus Anthura has been referred by us with hesitation to the 

 Anisopoda. In the figure given by Edwards, on Plate 31, of his 

 Crustace*s, the four anterior pairs of legs are thrown forward and 

 the three posterior backward. But in Costa's figure of a Naples 

 species in his Crustacea of the Fauna del Regno di Napoli, which 

 he calls the A. gracilis, the three anterior pairs are alike and are 

 thrown forward, and differ in form as well as position from the four 

 posterior pairs. Taking this species as the type of the genus, it is 

 a true Isopod, and the family Anthuridae should follow Idotaeidae in 

 the system. 



" 701. — The Idotaza annulata was taken in latitude 66° 16' south, longitude 

 106° 15' east. 



" 716. — In the characteristic of Philoscia, 7-articulatis should read 7-8-arti- 

 oulatis. We intended to make the genus rest on the fact, that the 

 antennae are not at all concealed at base, and not on the number of 

 joints. We doubt the value of either generic distinction. 



" 716. — Titanethes is a name given by Schiodte (Danske Vid. Selsk. Skr. 

 anden Raekke, ii.) to the Pherusa alba of Koch (Deutschlands Crus-
