LAOTIRA CAMBRIA (p. 32). 



Fig. 1. Fragment of a complex specimen which is weathered out in strong relief on a nodule. 

 Fig. 2. A 5-lobed individual partially buried in a thin nodule. It has been worn by recent abra- 

 sion so as to expose the radial canals and the central stomach. 

 Fig. 3. A complex specimen that is largely buried in a nodule. It is in strong contrast with fig. 1. 

 Figs. 4, 4a. A small distorted specimen in which two of the lobes have been greatly drawn out. 

 Fig. 5. A thin nodule with three many-lobed medusa? partially embedded in it. This is a character- 

 istic example of a large series of specimens of the same general type. 

 All figures natural size and reproduced from photographs.
