The author describes and illustrates Paraholinrlla cacsa nov. ; compares it with l\ 

 -Lvilliamso/il, to which it is closely allied. 



Paraholinrlla rugosa Brogger \ar., P. Iricrtlini Callaway, described by that author 

 under the genus Olenus in 1877. 



Triarllirns sliinetonensis Raw. The species named by Raw, Rep. Brit. Assoc, for 

 1907, p. 5)2, without a description or Hgure. 



The author compares it with T. spi/iosus Billings. 



Dr. Ami, Trans. Ottawa Field Nat., vol. 1, No. 4, 1882-83, indicates that Triarllirns 

 spinosus Billings, had spines on the 8th to 13th segment of the thorax. The English 

 species has 14 segments in the thorax, with the 12th axis ring spined. 



Genus Sphasrephthalmus Angelin. 



The author remarks that the genera Leptoplastus, Sphn?rophthalmus, C'tciiop\ge and 

 Eurycare, form a natural group of the Olenidae, characterized bv the fact, that the 

 cheek spines do not spring from the posterior angles of the head, but from the middle 

 of the external margin or even from the lateral angles. 



Brogger considers that all these forms should be placed in a single genus, which he 

 calls Leptoplastus, divided into four subgenera. 



The author describes Spliaeroplitlialmus alatus Boeck. This species is the same as 

 Olenus liumilis Phillips, 1848, according to Linnarsson's investigations of original 

 specimen. 



Spliaeroplitlialmus major nov. 



Ctenopyge: The author does not agree \vith Brogger and Moberg that only the 'axial 

 rings are fused, while the pleurae are free. Ehe jileurae seem to be closely connected 

 and rarely show any signs of separation. 



riie author describes Ctenopyge fusiforrnis nov., C. hisulratus Phillips. Salter, 

 taking Angelin's Spli. alatus figure as his guide, indicating it with Olenus hisulcatus 

 Phillips; therefore this species in English publications means Ctenopyf^e hisuliata or 

 some similar form. Ctenopyf^e faleifera nov., C. pecten Salter, C. expansa Salter, C. 

 teretifrons Angelin, described under the generic name of Sphaerophthalmus.
