pointed out by ^loberg [1899, p. 321], the two species belong to 

 dififerent stratigraphic horizons. //. kjer.idfi is found in the " grey- 

 wacke " below the zone containing Parad oxides olandicus Sjogren. 

 H. lundgrcni Moberg has been found only in the Lower Cambrian 

 sandstone. 



The only American species, Holmia rozvci [pi. 29], dififers in so 

 many characters that it is unnecessary to make comparisons between 

 the two species. 



The associated fossils at Tomten are OboIcUa nwbcrgi Walcott, 

 OboleUa (Glypfias) favosa Linnarsson, and ArioncUus. 



Dr. G. F. Matthew [1886, p. 472] identified " OlcncUns {?) 

 kjcntlfi '" from New Brunswick and Newfoundland. In his cata- 

 logue of species in the Cambrian Rocks of eastern Canada [1904. 

 pp. 260-278] he does not record the " 0. (f) kjernlH " under Olcncl- 

 lits or Hohnia. The specimens are not in the Matthew collection at 

 the University of Toronto, Canada, and under date January 6 and 

 March 18, 19 10, Dr. Matthew writes that he doubts if there is any 

 material representing Hohnia in the collection in St. John, as his 

 notes were based on fragments.

Only fragments of this species have been found, but these fortu- 

 nately include one nearly entire cephalon [pi. 40, fig. 4]. All the 

 specimens occur in a hard, compact, fine-grained sandstone. Through 

 the courtesy of Dr. Moberg I received casts of the typical specimens 

 described by him, also a few good fragments, of which three are
