ZOOLOGY AND BOTANV, MICROSCOPY, ETC. 45 



British Museum Blattidge in Amber.* — E,. Slielford makes a report 

 on Olis^ocene species from East Prussia and Samland, Miocene species 

 from Stettin (including four new species), and African species of un- 

 known geological horizon (including three new species). 



3. Myriopoda. 



Indo-Malayan Glomerids.f — K. W. Yerhoeff establishes two new 

 genera, Malai/omeris and Hyleoglomeris, the latter with two species. 

 TVhile the majority of our European Glomerids are brightly marked, the 

 Indo-Malayan forms (hke these three new ones) are monotonous and with 

 little pigment. Verhoeff suggests that this is in relation to their life in 

 dark places — among talus and in the forest. 



8. Arachnida. ' S 



Celebes Spiders.:]: — P. Merian makes an important addition to our 

 knowledge of spiders and their geographical distribution. Over fifty 

 new forms are described and about 100 others are dealt with. The 

 mountains and volcanoes of Celebes have a quite peculiar and sharply 

 defined Aranean fauna, as is also the case with the Andes. The general 

 results of the autlior's studies on the distribution of spiders in Celebes go 

 to corroborate the views of the brothers Sarasin. 



Fisherman's Spider. § — C. AY. de Vis describes a new sub-species of 

 Nephila maculata, which he names jyiscatorum, and writes as follows : — 

 " That the fishermen of Papua use the web of a spider as a bait and 

 tangle, by means of a kite, in their capture of fish, has already been 

 made known to us, and we are now informed that aboriginals on the 

 fringe of our mainland employ for a like purpose the same substance, 

 though not in the same manner." The spider, whose web is said to be 

 used in fishing, was sent to the author for identification, and he de- 

 scribes it as noted above. 



Pantopod Larvae. |1 — V. Dogiel has studied in particular the nervous 

 system and glands of the larvae of various Pantopods— of the families 

 Nymphonida3 and Pycnogonidte, e.g. Nymphon sfrdmii, Ghsetonymphon 

 spinosum, and Pycnogonum littorale. He deals with the innervation of 

 the limbs and the proboscis, the sensory system, the motor system, the 

 visceral system, and the central system. As regards glands, he describes 

 those of the basal joints of the legs, of the claws, and of the skin. 

 Dogiel deals at some length with the enigmatical " ventral organs," 

 which seem to be vestigial structures. In some respects they seem to 

 be glandular ; in other respects they seem like sensory structures.

Sexual Changes in Blood and Liver of Carcinus maenas.f — Geoffrey 

 Smith finds that the blood of this crab exhibits three chief conditions —
