of Tegenaria Guyonü and description of certain organs in the male abdominal 
sexual region, by J. Maule Campbell. Two cases were related in which 
during confinement the males killed the females after union and an instance 
was also given of an attempt to impregnate an immature female which was 
also destroyed by the male. In neither case could hunger have been the 
cause of the attack. The writer explained these occurrences and also the 
accounts of females destroying males after union on the ground »that those 
instincts which are habitually practised throughout the far greater portion 
of the life of the species, and on which its existence is dependent would 
scarcely be suspended for a longer period than necessary for the sexual union«. 
Some of the habits of Spiders and especially of this species were mentioned 
as bearing on these sexual conflicts, and the specific benefits which would 
arise from them were referred to. The paper concluded by a note on some 
glands situated on the convexity of the abdominal sexual region. The ducts, 
considerably convoluted, open through transparent tubular spines which are 
arranged transversely to the axis of the body of the spider. These organs 
are supposed by Mr. Campbell to be a kind of spinning organ. Two pa- 
pilla like processes below the opening of the genital sinus were also descri- 
bed. — J. Murie.
