Dr. Sharp exhibited a number of stag beetles {Lucanidcs) from various parts of 

 the world, calling attention to the trimorphism conspicuous among the males of 

 many species. They differ not only in size, but also in the form of the mandibles, 

 and can be usually placed in three well-marked groups in each species. He also 

 exhibited some bees of the genus Koptorthosoma from Ceylon, in which in the 

 female a cavity is formed in the anterior end of the abdomen by an involution of 

 the skin. The abdomen is pressed so close against the thorax that in the normal 

 position this cavity is invisible, but it can be seen by bending down the abdomen or 

 by cutting it off. The cavity varies in form in different species, but is found 

 throughout the genus in the female, and always contains a number of large Acari, 

 It is not known whether these parasites have any connection with the development 

 of the structure in question. Dr. Harmer, an Ampliipod Crustacean of the genus 

 Niphargus, found in a well at Norwich. This genus is only known to occur in deep 

 ■wells, and in the complete absence of pigment from all parts of the body, including 

 the eyes, it resembles a cave-animal. — L. Doncasteb, Hon. Sec.
