XXI. — On the Budding of the Cuninse in the Stomach of 

 the Gerjonidse. Bj 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 Hiickel in his ' Monographic der 

 Riisselquallen ') are very incomplete, I bestowed particular 

 attention upon this supposed Geri/onia-hrood, with the pur- 

 pose of tracing their still entirely unknown development, and 

 testing more accurately the hypothesis put forward by Hackel as 

 to the genetic connexion of the Geryonidas with the vEginidae. 

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

 succeeded in observing a tolerably continuous series of the 

 developmental stages of these Cicnina'j and in arriving at the
