ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 571 



first jaw is simple in all the specimens, there being no trace of any 

 accessory tooth ; the second jaw has four clearly-marked teeth and one 

 minute accessory tooth. In the number of legs and the structure of 

 the jaws P. gilesii differs from all other Australasian species of either of 

 the genera, Peripatoides or Ooperipatiis. 



y. Myriopoda. 



Studies on Centipedes.* — F. Silvestri continues his investigations 

 on Chilopoda. He gives descriptions of some genera and species of 

 Henicopidte, including Lamyctinus g. n., Esasligmatobius g. n., and of 

 some genera and species of Geophilomorpha, including species of 

 Aphilodon, Mecophilus, and Apogeophilus. 



Ethiopian Myriopods.f — Carl Graf Attems reports on a collection 

 from " a region which has been but little explored in this connection." 

 The collection includes twenty species, of which seven are new, e.g. 

 Amurus drepanopus, Oxydesmus anacanihus, Lissopyge neumanni, and 

 ObeJostreptus acifer. 



Abnormal Pair of Appendages in Lithobius.J — L. Doncaster calls 

 attention to the occurrence of an extra pair of appendages between the 

 poison-claws and the second maxillge. The mandibles and both pairs of 

 maxilla? appeared to be perfectly normal, and behind the normal pair of 

 poison-claws there were as usual fifteen pairs of walking-legs. The 

 extra appendages were more nearly like poison-claws than any other 

 appendages of Lithobius, but differed in several important details. 



8. Arachnida. 



Vagina of Lycosidse.§ — T. H. Jarvi notes that it is customary to 

 regard the " epigyne " in Lycosid spiders as a median " groove," in 

 various ways divided by a median septum. He sees in. the epigyne 

 two paired integumentary furrows, which start from the anterior margin 

 of the vaginal opening and run forwards. The furrows are continued 

 for a very short distance into the delicate chitinous ventral (anterior) 

 wall of the vagina. In Lycosidae the primitive type of epigyne is 

 marked by a superficial pair of furrows extending forwards from the 

 margin of the vaginal opening. They are really to be regarded as 

 derivatives of the openings of the receptacula. Starting from this in- 

 terpretation, the author makes a scheme suggesting the probable evolu- 

 tion of the various types of vaginae in Lycosidre. 



Oriental Solifuga3.|| — A. S. Hirst describes a number of new species 

 of Galeodes from the Indian Museum — 0. aulicus, G.festivus, G.annan- 

 dalei, etc., and Eusimonia celeripes, also new. He gives a useful key 

 showing the principal differences between the males of the species of 

 Galeodes.
