Lagena squamosa.

The aperture of this flask-shaped foram is toward the bottom in this micrograph. The scattered holes in the sides of the test (as opposed to the ones in the raised ridges) were probably generated after death; this sample dates from the Pliestocene. Image courtesy of R. Timothy Patterson, Carleton University. This image originally appeared in J. Foram. Res. 17:212-226 and is used with permission.

Notice the asymmetry of the raised ridges (called costae). Image courtesy of R. Timothy Patterson, Carleton University. This image originally appeared in J. Foram. Res. 17:212-226 and is used with permission.

Lagena formosa.

Individual collected in Saanich Inlet, Vancouver Island, British Columbia. The aperture is toward the bottom. Image courtesy of R. Timothy Patterson, Carleton University. This image first appeared in J. Foram. Res. 28:201-219 and is used with permission.

Sample collected at Hamble Estuary, Hampshire, England. This stenohaline species generally penetrates the estuary only as the salt wedge advances during the drier summer months.

The slot-like aperture through which the foram's reticulopodia pass is clearly visible in this image. Sample collected at Hamble Estuary, Hampshire, England.

This specimen was collected in 1960 in the Timor Sea (near Indonesia). Image courtesy of R. Timothy Patterson, Carleton University. This image originally appeared in J. Foram. Res. 17:212-226 and is used with permission.

This fossil (Quaternary) foram has an unusual divided aperture, which is visible at the bottom of the test. Image courtesy of R. Timothy Patterson, Carleton University. This image originally appeared in J. Foram. Res. 17:212-226 and is used with permission.

This fossil foram was found in Upper Cretaceous (Taylor Group) strata in Texas. This is a side view, with the aperture toward the bottom. Image courtesy of R. Timothy Patterson, Carleton University. This image originally appeared in J. Foram. Res. 17:212-226 and is used with permission.
