ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 47 



limits of the Chirocephalidae are not very precise, but its sub-families 

 Chirocephalinas and Eubranchipodinae are uniform. The sub-family 

 Branchinellithe is divergent in the structure of the penis. 



The author gives a genealogical tree, and inclines to the conclusion 

 that the sub-order has had a polyphyletic origin — a view that is corro- 

 borated by the facts of geographical distribution. 



New Antarctic Phyllopod.* — Eugene Daday de Dees describes 

 Branehinecta gaini sp. n.,a new Anostracan Phyllopod found by L. Gain 

 of the ' Pourquoi-pas ? ' Expedition in Petermann Island and adjacent 

 islands. It was found in crevices among the rocks where water collected 

 from melted snow. It is like some of the northern species, but seems 

 distinct, and is the first Antarctic representative of its race. 



Affinities of Philichthydae.f — A. Quidor has studied the life-history 

 and affinities of Leposphilus labrei Hesse parasitic on the scales of Labmis 

 donovani. In their first parasitic stages the Philichthydse show relation- 

 ship with the Dichelestidaj ; in their free stages they show relationship 

 with such Lernaeidse as Lernsea and Penella. It seems likely that the 

 Philichthydae should be ranked as intermediate between Lernaeidas and 

 Dichelestidae. 



Parasitic Copepod from Cephalodiscus.J — W. T. Caiman describes 

 Zanclopus cephalodisci g.etsp.n., one of the Ascidocolidas, found in 

 Cephalodiscus. It is most nearly allied to EnUrognaih,us comatidse of 

 Giesbrecht ; it also approaches Enteroeola, Aplostoma, and Enteropsis in 

 the vermiform or maggot-shaped body and non-natatory thoracic feet of 

 the female, and in the absence of a brood-sac and of maxillipedes ; but 

 it is a very distinct type. 



Ostracods from Funafuti.§ — Frederick Chapman reports on fifty-two 

 species and varieties of Ostracods from near Funafuti, eight of them from 

 great depths (2^ to 3 miles). Nine new species of Cythere and other 

 genera are described, and Brady's Pliocene Loxoconcha latissima is noted 

 for the first time as recent. 



Notes on Cladocera.|| — E. A. Birge discusses Pseudosida bidentata 



Herrick and the genus, Latona parviremis sp. n. and the genus, Latonopsis 



fascicidata Daday, Wlassicsia hinistinensis sp. n., Odontalonag.n. (erected 



for Alona tenuicaudis Sars and 0. longicaudis sp. n.), and the genus 



Alonella. 



Annulata. 



Cuticular Warts of Pilargis verrucosa. IT — Ch. Perez found at 

 Arcachon an interesting Polychset described by Saint-Joseph under the 

 name Pilargis verrucosa. Its thick cuticle is more like that of an 

 Arthropod. There are no mucous glands, and the whole dorsal surface 

 is studded with peculiar warts, almost wholly cuticular.
