Similar to the foregoing but with pores or meshes of the sponge 

 reticulation about 10 mm. wide. In this variety sometimes 

 bulbous extensions in the processes are met with. With these, 

 extensions of the pseudogaster correspond. In these swellings, 

 moreover, the pseudogaster has a diameter equal to half that of the
