[or Colossendeis) Smitliii. 265 



long ago described by Sabine (Appendix Capt. Parry's 

 Voyage, p. exxvi), and Anomorhynchus Smithii (as I learn 

 from his letter) as also referable to the same species. Sabine's 

 species was unfortunately never figured ; but I may note that 

 our specimens differ from his descriptions in being destitute 

 of eyes and without any distinct transverse line on the first 

 segment of the body, and from that of Jarzynsky in having 

 the first pair of appendages 9- (not 10-) jointed ; nor do the 

 words of the latter author — " Pedes (tenues) tarso longissimo 

 (manu multo longiore) ; appendix caudata longissima cylin- 

 drica, extrema parte iucrassata " — apply to our types. In other 

 particulars his description is fairly applicable to A. Smithu. 



From Colossendeis augusta, Sars, our species is apparently 

 distinguished by the form of the rostrum, the relatively 

 longer postabdomen, shorter conical oculigerous tubercle, and 

 perfectly distinct claws of the accessory legs. 



Sabine's original types of Plioxichilus i^rohoscideus were 

 found at ebb-tide on the shores of the North Georgian or Parry 

 Islands, the type specimens of Colossendeis horealis near the 

 shores of Russian Lapland (" ad oras LapponijB rossicge ex- 

 ad verso insulis Gabriliensibus ad semi-insula3 piscatoriee, 

 maxima profunditate maris 120-250 org."). A single speci- 

 men is referred to by Prof. Sars as having been obtained in 

 the cold area west of the Norwegian coast in lat. 62° 41 ''5 N., 

 long. 1° 48' E., at a depth of 412 fathoms, by the Norwegian 

 expedition in 1876 {t. c. pp. 337-368). Colossendeis augusta 

 was obtained by the same expedition in lat. 63° 10'*2 N., long. 

 4° 59'- 6 E., in 417 fathoms. 



The examination of a larger series of specimens is needed to 

 show whether the species above mentioned are all of them dis- 

 tinct; in the meantime, to avoid future confusion in the synony- 

 ma, I have thought it desirable to call attention to the memoir 

 of the Russian naturalist, which has (excusably) been over- 

 looked by nearly all the recorders of zoological literature"^. 



* Since tliis note lias been in type, I have received from Dr. P. P. C. 

 Hoek a paper containing an account of the Pycnogonids dredged during 

 the cruises of the ' Willem Barents/ in the years 1878-79, reprinted from 

 the ' Niederl. Archiv f. Zool.' Supplementb. i. (1881). lu this paper a 

 species is figured under the name of Colussendeis jjroboscideics, Sabine, 

 with which, notwithstanding some slight differences, I must regard Auo- 

 morhynchus Smithii as very probably identical. The genus Colossendeis 

 is not described by Dr. Hoek ; but the memoir of Jarzynsky is cited as 

 having been published in the ' Auuales de la Societe des Naturalistes de 

 St. Petersbourg,' 1870, a publication 1 have never seen. We are informed 

 in Dr. Hoek's memoir that four female examples of C pi-oboscideus were 

 recently collected by Mr. Murray of Edinburgh in lat. 00'-^ 3' N., between 

 the north of Scotland and the Faroes ; also numerous forms of the same 

 genus inhabit southern latitudes (as shown by the rich materials collected 

 by the * Challenger ' expedition), from all of which C. proboscideus is dis- 

 tioguished by its " highly concentrated " body.
