The author considers Pseudoaspluis Sclitnich av tlic next step in tlie development from 

 Basiiicus and Ogygites. 



The author is in error in liis remartcs that Brongniart applied the name of Ugygia 

 to O. bucliii and (). dilatata with forked hypostoma. Brongniart applied the name to 

 an Asaphus. The second species described by Brongniart, according to Tromelin and 

 Lebesconte, ibid, p. 34, has the entire hypostoma characteristic of O. desiderata Barr.

The author illustrates Brachyaspis notatis Billings. Ogyi^ites tuiindetisis Chapman. 

 Remarks: this species has a forked hypostoma, and siiould not be included under the 

 genus.

■ Some changes in the naiiics of ocncra of TriloMtc-^. 



The Ottawa Naturalist, vol 26, Feb., 1913. 



The author remarks on the ten new genera described b\- Jaekel in Zeit. d. Deutsch 

 Geol. Ges., vol. 61, pp. 380-401, 1909, should be rejected ami referred to older names 

 as follows: 



Paragnostus to Condylopyge Corda, Dichagnostus to Pleuroctenium Corda, Mesag- 

 nostus to Peronopsis Corda, Miagnostus to Lejopyge Corda, Leiagnostus to Phalacroma 

 Corda, Metagnostus to Arthrorhachis Corda. Tliese six new genera the author rejects. 



The author would reject Microdiscus Emmons, because it was founded on a \oung 

 specimen of the' genus Trinucleus, and substitutes Eodiscus. This would overlook 

 Salter's Microdiscus — the generic name shoidd read Microdiscus Salter (not Emmons). 



Raymond, who examined the type specimen of Pempliigaspis hullata Hall, does not 

 place it with Microdiscus, as suggested by Walcott. 



The author is in favor of using Green's generic name Cr\ptolithus for Murchison's 

 genus Trinucleus. This generic name has long been used by Broiin, Cioldfuss, Emm- 

 rich, Angelin, Foerste and Vogdes. Eaton's genus Nuttainia of 1832 not used. Dr. 

 Jacob Green claimed priority in his Monograph of Triiobites. The generic name was 

 first described in Am. Jour. Geol., June, 1832. 



The author uses Ogygites, Tromelin and Lebesconte, for primitive Asaphinae, \vith 

 annuiated pygidia and forked hypostomata, and Ogygiocaris Angelin, for Ogygia 

 Buclii and 0. dilatata. 



The author favors the adoption of Goldius for Brontes and Bronteus. For Acaste 

 (loldfuss, the author takes the generic name Phacopidella. Reed, 1906, as Leach in 

 1811, used the first genus for a genus of Cirripedes. Arges was used by Ilaan in 

 1835, and the author uses Ceratarges Gurich, for the generic name; also Aulacojdeura 

 Corda, in place of preoccupied generic name Arethusina Barrande.
