Zoological results of a tour in the far east : Polyzoa Entoprocta and Ctenostomata
The Polyzoa discussed or described in this paper are all from fresh or brackish water. The majority are from the Tale Sap in the north-eastern part of the Malay Peninsula} but a few come from the Tai-Hu in the Kiangsu Province of China. I have also included notes on one Indian form. The following species are to be considered: ENTOPROCTA. Chitaspis athleticus, gen. et sp. nov., from the Tale Sap. CTENOSTOMATA. Alcyonidium mytili, Dalyell, from Indian estuaries, etc. Triticella pediceltata (Alder), from the Tale Sap. Bowerbankiacaudata, Hincks, from the Tale Sap and Perak. Paludicella elongata, Leidy, from the Tai-Hu. Paludicella pentagonalis, sp. nov., from the Tale Sap. Victorelta bengalensis, Annandale, from the Tale Sap. Hislopia cambodgiensis (Jullien), from the Tai-Hu. Hislopia malayensis. sp. nov., from Jalor in the Malay Peninsula. It will be as well to defer consideration of the biology and distribution of these species until I have been able to deal systematically with the Phylactolaemata and Cheilostomata collected on my tour. All that need be said here is that while the species of Paludicella and Hislopia are from fresh water, the others. on the list are from brackish water
Almost periodic solution in distribution for stochastic differential equations with Stepanov almost periodic coefficients
This paper deals with the existence and uniqueness of (-pseudo) almost
periodic mild solution to some evolution equations with Stepanov (-pseudo)
almost periodic coefficients, in both determinist and stochastic cases. After
revisiting some known concepts and properties of Stepanov (-pseudo) almost
periodicity in complete metric space, we consider a semilinear stochastic
evolution equation on a Hilbert separable space with Stepanov (-pseudo)
almost periodic coefficients. We show existence and uniqueness of the mild
solution which is (-pseudo) almost periodic in 2-distribution. We also
generalize a result by Andres and Pennequin, according to which there is no
purely Stepanov almost periodic solutions to differential equations with
Stepanov almost periodic coefficients
