upon the carapace, and by the existence of two spiniform teeth upon the 
upper surfaee of the ophthalmie ring. ‘The terminal joints of the large 
prehensile limbs (griffes) have seven teeth. Length, 34 inches." 
Hab.: Auckland Islands; Laurie Harbour. (“ Coll. Brit. Mus.") Chili. 
(Mus. Paris.) 
In the example in the British Museum collection the carapace is smooth, 
with two longitudinal grooves above, and somewhat emarginate behind, the 
antero-lateral angles being armed with two small spines. The rostral plate 
is semi-oval, and rounded at its distal extremity. The spines upon the 
ophthalmic segment are small but distinct, There are two longer spines 
upon the basal joint of the antennules. There are six longitudinal carine 
upon each of the first six segments of the abdomen, which terminate poste- 
riorly in spinules upon the fourth to sixth segments. There is a high 
median longitudinal ridge terminating posteriorly in a spine upon the ter- 
minal segment, which has six longer marginal spines, besides the small 
intervening spinules. 
The specimen from Auckland Islands agrees with Milne Edwards’ 
short diagnosis, and in all important particulars with the longer description 
in the “ Historia de Chile,” except that in that description no mention 
is made of the small spines at the antero-lateral angles of the carapace. 
Art. LXV.—Notes on the Genera Astacoides and Paranephrops. By 
Epwarp J. Mrs, Assistant in the Zoological Department, British 
Museum.* 
Iw the ** Annals" for last month Professor J. Wood-Mason published a very 
interesting note ** On the Mode in which the Young of the New Zealand 
Astacide attach themselves to the Mother." He states (p. 806) that he 
observed this peculiar mode of attachment in the young of “a female of 
Astacoides zealandicus,” which, he adds in a foot-note, *« = Paranephrops 
setosus, Hutton ;” and, in another foot-note, he cites the genus Paranephrops 
of White as synonymous with Astacoides of Guérin-Méneville, As it appears 
to me still uncertain to what species Professor Wood-Mason refers in his 
communication, the following observations may be of interest. 
"Guérin-Méggrille founded the genus Astacoides, in April, 1889,+ for a 
species of Craytisn described as oceurring very frequently in the rivers of 
Madagascar, to which he applied the name of A. goudotii, after its dis-
