by himself in the Philippine Sea, including the interesting Crus- 

 taceous genus Leucifer Reynaudi. The same animal, long ago 

 carefully figured by Thompson, in his ' Zoological Eesearches,' 

 has also more recently been studied by Glaus (Zeitsch. f. Wiss. 

 Zool. 1863) and Dohrn (ibid., 1871). 



To Dr. Glaus we are indebted for a valuable memoir on the 

 very interesting genus Nebalia (published in the ' Zeitschr. f. 

 Wissench. Zoologie,' 1872, p. 323, pi. xxv.), and also an inquiry 

 into the history and different supposed species of the parasitic 

 genus Fhromma, generally found in the sac-like bodies of Beroe 

 and Pyrosoma (ibid., p. 331, plates xxvi. and xxvii.) 



Mr. Brady has continued his series of contributions to the 

 study of the Entomostraca, by publishing a list of the non- 

 parasitic Gopepoda of the North-East Goast of England, with 

 two plates, in the 'Annals of Natural History,' July, 1873. 



At the meeting of the Societe Helvetique des Sciences Natu- 

 relles, held at Fribourg in August last, M. Vogt gave a summary 

 of the results of his researches in the genera Branchipus and 

 Artemia, the most remarkable fact being that amongst the Arte- 

 mise collected during the months of July and August there are no 

 males, and that the females propagate by parthenogenesis (Ann. 

 of Nat. Hist., Nov. 1872). 



The genus Limnadia, interesting not only for its large size 

 amongst the bivalve Entomostracous Grustacea, but also for the 

 vast numbers in which it occurs in the fossil state, has now 

 afforded an Australian species, which has been illustrated by 

 Professor Glaus, in the ' Zeitschrift f. Wissench. Zool.,' 1872, 

 p. 855, pi. xxix. and xxx. 



Directing our attention next to the Arachnida, a " General List 

 of the Spiders of Palestine and Syria, with Descriptions of 

 numerous new Species, and Gharacters of two new Genera," has 

 been published in the ' Illustrated Proceedings of the Zoological 

 Society of London' (1872, Feb. 20). Exclusive of the Acaridea, 

 Phalangidea, Solpugidea and Scorpionidea, 278 species of true 

 spiders were collected by the author himself on the plains of the 

 Jordan near Elisha's WelL The two new genera are Palaestina 

 and Githaeron, both belonging to the Agelinidse, and the already- 

 known species amounted to 127, the new ones being 151 in number. 

 Four excellent plates full of figures illustrate this memoir.
