DESCRIPTIONS OF GENERA AND SPECIES 



677 



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- 

 chueta ; 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, ROSA found only 

 two pairs in xiv and xv. 



ROSA 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 ; 

 the type-species of the genus is

This species is evidently nearly allied to the last ; but the above definition shows 

 divergences ; in addition to the points of difference there enumerated, it is possible 

 that there are differences in the setae. In both species the setae do not commence 

 before the sixteenth segment ; but in the present species the setae are stated by
