— the ramus uniarticulate, Telson sqiiamiforni, cleft to the base." Mr. Haswell adds the 

 remark that iu most of its characters this genus " approaches Allorchestes — being 

 distinguished from that genus only by the largely developed anterior coxaj and the 

 character of the telson." For his subsequent view of the position of this genus, see Note 

 on Haswell, 1885.

M. Jourdain concludes that the cylindres a batonnets so commonly met with on the upper 

 antenna) (antenne interne) of Crustacea, both podophthalmic and oligognath, are certainly 

 organs of sense ; but, relying only on anatomical structure apart from physiological 

 experiment, we have no right to affirm that these cylinders "sent affect^s a I'olf action." 



1880. KossMANN, RoBBY, bom November 22, 1849 (P. Mayer). 



Zoolosrische Er2;ebnisse einer im Auftraa;e der koni^lichen Academic der 

 Wissenschaften zu Berlin ausgeftilirten Reise in die Kustengebiete des rothen 

 Meeres. Herausgegeben mit Unterstiitziing der koniglichen Academic von Robby 

 Kossmann, Zweite Halfte, Erste Lieferung. Leipzig, 1880. 



In the order Lsemodipoda, pages 126-128, Kossmann describes " ProteUa Danx," n. s., Taf. xii. 

 Fig. 1-7, and Protella nuhspinosa, n. s., Taf. xii. Fig. 8, 9. Both of these are considered 

 by Mayer to be young forms of Protella phasma, Montagu. 



In the order Amphipoda, pages 129-140, he first of all observes that he cannot acquiesce in that 

 accentuation of small, and generally merely sexual, distinctions in the form of the gnathopods, 

 which has led to the separation of the genera Talitnis, Orcliestia, Orcliestoidea and 

 Talorchestia. He prefers to group in the genus Urchestin all forms of the family with short 

 upper antennce and without ungues on the maxOlipeds. He then describes Orcliestia 

 fissispinosa, n. s., Taf. xiii. Fig. 1-5, from a form probably female, in which the first 

 gnathopod is not in the least cheliform, the second gnathopod has a dactjdus which ends in 

 a pointed spine, and also has fine spinules on the whole inner rim, while the rest of the 

 rim is quite bare. The figure shows a hand, terminally rounded, projecting much beyond the 

 •' daotylus. 



It must here be observed that, if the four genera above-named are united, Talitruft takes 

 precedence of Orcliestia, and, in fact, if they are kept separate, Orcliestia is the only one of 

 the four in which Kossmann's species cannot stand. Provisionally it may be called Talifrw 

 fissispinosus, but the possibility remains that a single specimen 5 mm. iu length may be the 

 young of some previously known species.
