Two Species of Lagena

At the moment I am trying to complete an illustrated booklet on the Foraminifera from my digital pictures and I have just been distracted by these two species of lagena. As usual with only the resouurces of an amateur I am not too sure about this pair. As usual Cushman always comes up with something but sadly the illustrations are never so good for certainty. Please click on the image for a larger image. Any help would be appreciated BD.
