walcott.] PALEONTOLOGY NEW BRUNSWICK. 83 



The third contribution by Mr. Matthew, 1 presented to the Royal So- 

 ciety of Canada in 1885, treats of the Protozoa, Hydrozoa, Brachiopoda, 

 Pteropoda, Gasteropoda, Phyllopoda, Ostracoda, and some of the Tril- 

 obita. 



Of the Protozoa, Archwocyathus f pavonoides, Protospongia f minor, 

 P. f minor, var. distans, the new genus Eocoryne and the species Eoco- 

 ryne geminum are described. Of Hydrozoa Dendrograpsus t primordialis 

 Protograpsus, n. g\, with the species Protograpsus alatus. But one spe- 

 cies of the Echinodermata is mentioned, Eocystites primc&vus of Billiugs. 

 The new forms of Brachiopoda are : Lingulella f inflata, L. linguloides, 

 Acrotreta baileyi, A. f gulielmi, Kutorgina latourensis, K. f pterineoides, 

 Orthis quacoensis. Of species previously described Lingulella dawsoni, 

 Linnarssonia transversa Hartt, Linnarssonia misera Billings, Acrothele 

 matthewi Hartt, and Orthis billing si Hartt, are described and illustrated. 



Amoug the Pteropods the new subgeuus Oamerotheca is proposed, 

 and the species Hyolithes (Camerotheca) gracilis, H. {€.) danianus, aud 

 H. [G.) micmac are described and illustrated. The genus Diplotheca 

 includes Diplotheca hyattiana and the variety caudata ; also Hyolithes 

 acadicus of Hartt, and its varieties, sericea, obtusa, and crassa. 



The Gasteropoda include a notice of the genus Stenotheca and the 

 description of the new species, Stenotheca hicksiana, S. concentrica, S. ra- 

 dio ta, S. nasuta, and S. triangularis. The subgenus Parmophorella is 

 proposed to include the original species, Distinct acadica Hartt. Steno- 

 theca acadica and Harttia matthewi Walcott are described and illus- 

 trated. To the Phyllopoda (?) the new genus Lepiditta. with the species 

 L. alata and L. curta, and the new genus Lepidilla, with the species 

 Lepidilla* anomala, are referred. Mr. Matthew says that these forms 

 are very minute, and belong either to lamellibrauchs or Phyllopoda. 

 The Ostracod Crustaceans include the new genera Hipponicharion and 

 Beyrichona. One species is referred to the former genus, H. eos, and 

 two to the latter, B. papilio and B. tinea. To the genus Primitia he 

 refers one new species, P. acadica. 



The Trilobita include the new species of Agnostus, A. regulus, A. 

 vartitus, A. vir, A. vir. var. concinus, A. tessella, A. umbo, A. obtusilobus, 

 and A. acutilobus. Agnostus acadicus Hartt is described and figured aud 

 the variety declivis proposed. Microdiscus pulchella Hartt is placed as 

 a variety of M. punctatus Salter, and a new variety, precursor , is pro- 

 posed to be included under punctatus. M. daicsoni Hartt is also described 

 and figured. Of the larger forms of the Trilobita, Agraulos (?) arti- 

 cephalus is proposed, Solenopleura acadica of Whiteaves is figured and 

 described for the first time, and Paradoxides abenacus is proposed as a 

 new species. A redescription of Paradoxides micmac and the proposal 

 of a variety, suricus of P. acadicus concludes the references to previ- 

 ously described species.
