12. The Larva of the Pin-cushion Starfish (Porania pulvillus (O.F.M.). 
By Dr. James F. Gemmiuu. 
The period of ripeness in the Firth of Clyde is from about the middle of 
April till about the end of May. The eggs are small, and development is 
indirect, the general larval history resembling that of Asterias rubens. The 
late larva is a brachiolaria with a well-marked sucker and numerous small 
papille on and between the brachia. This stage was reached in a culture 
eight weeks old which was made at the Millport Station and kept without 
change of water in a small aquarium holding about three-quarters of a gallon, 
under ‘convection current’ circulation at Glasgow University. Features of 
much interest are (1) the presence in early larvee of possible rudiments of a 
posterior enteroccelic outgrowth; (2) the occurrence among the later larve of 
several specimens with double hydroccele formation, and (8) the presence alike 
in normal and in double-hydroceele larve of a ‘madreporic’ vesicle the floor of 
which contracts rhythmically during life. 
13. Mr. W. A. Lamborn’s Observation on Marriage by Capture by a 
West African Wasp. A possible Explanation of the great Variability 
of certain Secondary Sexual Characters in Males. By Professor 
E. B. Poutton, F.R.S. 
A letter recently received from Mr. W. A. Lamborn, Entomologist to the 
Agricultural Department of Southern Nigeria, records the following interesting 
observation made near Ibadan :— 
“On July 10, 1913, a large clay nest was found attached to the under side 
of a Kola leaf. On the nest was a large wasp which had enormously developed
