K. michaelsenii) are in segment xiii; as to egg-sacs nothing is known. The 

 spermathecae show the same differences in different species that they do in Micro- 

 chaetaj in K. madagascariensis and K. longus there are a vast number of small 

 pouches in segments xiii, xiv, xv, or xv, xvi; in K. michaelsenii, KosA found only 

 two pairs in xiv and xv. 



EosA believes that this genus is synonymous with Geophagus; but as the latter 

 name is already pre-occupied for a genus of fishes, the name Kynotus must stand ;
