XXI. — On the Budding of the Ciminge iji the Stomach of 

 the Geryonidse. By B. Uljanin ■^. 



During my sojourn in the winter of the present year at Villa- 

 franca and Naples, I had many opportunities of observing 

 specimens of Carmarina hastata^ Hiick., which bore Cunina- 

 buds in their stomachs. As the most detailed extant observa- 

 tions on these buds (those of Hackel in his ' Monographic der 

 Russelquallcn ') are very incomplete, I bestowed particular 

 attention upon this supposed 6''er^o« ?'a-brood, with the pur- 

 pose of tracing their still entirely unknown development, and 

 testing more accurately the hypothesis put forward by Iliickel as 

 to the genetic connexion of the Geryonidic with the ^Eginidfe. 

 My hopes, however, were only partially fulfilled. I certainly 

 succeecled in observing a tolerably continuous series of the 

 developmental stages of these Cicninfc, and in arriving at the
