taceen, etc., Heft, xxxiv. 24), a species of Lyginae, without eyes, and 

 having a narrow head but slightly transverse, with the anterior 

 angles projecting. 

 Page 717. — Insert the heading, Pedes posteriores valde elongati, after the charac- 

 teristic of Genus 5, directly before that of Genus 6. 



" 738. — Under Lygia JEhrenbergii, add reference to Brandt's Conspectus, 

 and to Edwards's Crustace's, iii. 157. 



" 741. — Under Lygia Gfaudichaudii, add the reference, Edwards's Crus- 

 taces, iii. 157. 



" 746. — The genus Desmarestia of Nicolet (loc. cit.) is near Cymothoe in its 

 ancoral legs, but the abdomen is only two-jointed. The thorax is 

 broad elliptical, the abdomen hardly half as wide as its greatest 

 breadth ; the four antennae nearly equal. It is near Orozeuktes. 



" 851. — The genus Nicea of Nicolet (loc. cit.) may possibly be the same 

 with Allorchestes ; but the essential characteristics are not given, 

 excepting the non-palpigerous character of the mandible. Even if 

 identical, the genus does not antedate the author's, as the description 

 of Allorchestes was first published on July 1st of 1849. The max- 

 illipeds are peculiar in having the surface tuberculate, and the 

 inner lamella is dentate only at apex, and there sparingly. 



w 855. — Orehestoidea tuberculata of Nicolet (loc. cit., PI. 2, f. 4) is the 

 author's Talitronus insculptus, and the genus Talitronus was insti- 

 tuted and published by the author, on July 1, 1849. The name has 

 been since rejected by him for Orchestia insculpta; and as Gay's 

 specific name is the older, it will become Orchestia tuberculata. 

 • We suspect that his Talitrus chilensis is what we have considered 

 the female of the 0. insculpta. 



« 882. — The locality of the Orchestia Pickerings was Kauai or Oahu, 

 Sandwich Islands. 



« 908. — Oallisoma^ Costa (loo. cit.), appears to be identical with Lysianassa, 

 The four anterior feet are not cheliform, and the second pair is 

 longer than the first. 



« 910. — Niphargus is the name of a new genus near Gammarus, proposed 

 by Schiodte, in Danske Vid. Selsk. Skr. anden Raekke, ii. The 

 author has not seen a description of it. 



" 918. — The genus Lalaria (L. longitarsis) of Nicolet (loc. cit., PI. 2, f. 8), 

 is between the Gammaridae and Corophidae, and appears to be iden- 

 tical with Aora of Krb'yer, which was also from Valparaiso. 



" 917. — The specimen of Uristes gigas was taken from the stomach of a 

 Penguin, in latitude 62° 28' south, longitude 101° 35' east, 



« 989. — The Tauria macrocephala was found in latitude 67° 5' south, 147° 

 42' east. The colour when alive was deep orange. 



« 991, — The name Daira of Edwards, is of more recent date than Daira of
