and three species of Flagellates, one new, have been found in 

 it by Goodey : " Observations on the Cytology of Flagellates 

 and Amoebae obtained from old stored soil " (Proc. Zool. Soc. 

 March 1916). 1 



Invertebrata. — A " Preliminary Notice of some Irish Sponges" 

 is given by Stephens (Ann. and Mag. Nat. Hist. No. 99, March 

 19 1 6), and contains an account of some monaxonellids of the 

 sub-order Sigmatomonaxonellida . 



Hargitt continues his studies on the Hydromedusse by 

 " Germ Cells of Ccelenterates : II. Clava leptostyla " (Journ. 

 Morph. vol. xxvii. March 191 6). 



The " Organs of Special Sense in Prorhynchus applanatus, 

 Kennel " (Journ. of Morph. vol. xxvii. March 191 6), aplanarian, 

 have been described and their histology figured by Kespner and 

 Taliaferro. Baylis contributes notes " On Crassicauda crassi- 

 cauda," a nematode and its hosts (Ann. and Mag. Nat. Hist. 

 No. 97, January 1916), and " The Nematode Genus Tanqua, 

 R. Richards " (ibid. No. 99, March 1916). Descriptions of a 

 number of worms, mainly Sabellidse, but some Terebellidse, are 

 contained in " Notes from the Gatty Marine Laboratory, St. 

 Andrews, No. xxxvii." (ibid. No. 97, January 1916) by M'Intosh. 

 In the Quart. Jour. Micro. Sci. vol. Ixi. March 1916, are two 

 papers on worm development. Haswell, " On the Embryology 

 of Stratiodrilus Histriobdellidce," shows that there is no meta- 

 morphosis in this form, and that the processes resemble those 

 in Rotifers. Gatenby describes " The Development of the 

 Sperm Duct, Oviduct, and Spermatheca." Experimental 

 results are recorded in " An Analysis of the Process of Re- 

 generation in certain Microdrilous Oligochsetes " (Jour. Exper. 

 Zool. vol . xx. February 1 9 1 6) . Cummings has notes on parasitic 

 insects in the Ann. and Mag. Nat. Hist. : on " New Species 

 of Lice " (No. 97, January 1916), and a " Note on the Thorax 

 in Anoplura and in the Genus Nesiotinus of the Mallophaga " 

 (No. 98, February 191 6), and in Proc. Zool. Soc. (February 1916) 

 he deals with the structure and development of the various 

 Anophura and Mallophaga obtained from animals in the Zoo- 

 logical Gardens. An interesting paper by Imms (Quart. Jour. 

 Micro. Sci. vol. Ixi. March 1916) treats of a subject indicated 

 by its title, " Observations on the Insect Parasites of some
