The material for this foi-m is inadequate for certain determination. 

 The small glabella and broad marginal fold show we are dealing with an 

 Anomocare, but the broken condition of the head-shield makes it uncer- 

 tain where the eyelobe is placed, and if the front margin is entire. 



A movable cheek, too small for the head-shiekl, figured, has the usual 

 broad fold, shallow furrow, and short obtuse flattened spine of an 

 Anomocare. 



A pygidium found with the head has a length about equal to the 

 width of the rachis and one side lobe. The axis has six rings and the 

 side lobes three obscure ribs ; the margin is flattened and without a fold. 



Another pygidium of larger size is wider, and has four or five rings 

 in the rachis ; there are only two faint ribs on the side lobes, and the 

 area of the limb is hollowed. 



Sculpture. — Surface of the head marked by minute punctations. 



Size. — Length of the head shield, 8 mm. ; width of the middle piece 

 at the front, 7 mm. ; at the eyes, 9 mm., and at the back, 12 mm. The 

 movable cheek figured is 8 mm. long and 3 mm. wide. The pygidium, 7 

 mm. long and 9 mm. wide. The other pygidium of Anomocaroid type, 

 10 mm. long and 20 mm. wide. 



Horizon. — Limestone bands of the gray shale. 



The head figured herewith, if of A. magnum, is that of a 3^oung 

 individual. The small pygidium figured does not belong to A. magnum, 

 but the larger one has a general resemblance to the type figured by 

 Brogger, and has the same number of ribs in the side lobes as the tail- 

 piece of that species. 



DOLICHOMBTOPUS, AngcHn. 



Among the genera of Eegio B. (Paradoxides beds), described by 

 Angelin, the above seems to be rare, as it has not been reported from 

 other countries than Sweden ; or if it has been found elsewhere, has not 

 been recognized and referred to its proper genus, A trilobite from Hast- 

 ings Cove seemed to come within Angelin's diagnosis, though evidently a 

 different species from his, and I therefore wrote to .Dr. G. Lindstrom, 

 keeper of the State Museum at Stockholm, for information regarding
