species of Agnostus and one of Hyolithes noted in association with 

 other species described by Mr. Hartt. 



In the year 1883 the fir.st of Mr. G. F. Matthew's 1 memoirs on the 

 fauna of the St. John group made its appearance. In this is given a 

 brief historical review of the work that had already been done upon 

 the fauna by Prof. Hartt, and a statement that from the collections made 

 from time to time during the progress of the Canadian geological sur- 

 vey in New Brunswick Mr. Billings identified fragments of Ellipso- 

 ccphalus and Salterella and the remains of two species of Hyolithes. 

 Besides these, there are the supposed plant remains of the genera PalaB- 

 ophycus, Eophyton, etc., of the higher divisions of the St. Johu 

 group. 2 Mr. Matthew made large collections, which were destroyed by 

 the great fire at St. John in the spring of 1877. His published studies 

 were based upon new material collected subsequently to that date. 



In the first memoir we find that he recognized three well defined spe- 

 cies of Paradoxides and six varieties, as follows : Paradoxides lamellatns 

 Hartt; P. lamellatus var. loricatus Matthew; P. acadicus Matthew; P. 

 eteminicus Matthew ; P. eteminieus y vars. suricoides, breviatus, qaacoensis, 

 malicilus, and pontijicalis. 



A review by Mr. C. D. Walcott 3 of the typical collections upon which 

 Prof. O. F. Hartt based his species, led to a revision of the genera and 

 species, with the following results : 



LiDguUi matthewi = Acrothele matthewi. 



Discina acadica = Palseacmea (?) acadica. 



Theca acadica = Hyolithes acadica. 



Agnostus similis ■= Agnostus acadicus. 



Microd incus pulchellu8...= Microdiscus punctatus Salter. 

 Conocephalites matthewi = Conocoryplie matthewi. 



gemini-spinosus = Cooocoryphe matthewi. 



bailey i = Conocoryplie baileyi. 



elegaus. — Conocoryphe elegans. 



robbi = Ptychoparia robbi. 



formosus = robbi. 



ouangoudiauus = ouangondiana. 



aurora = ouangondiana var. aurora. 



qnadrata = quadrata. 



orestcs = orestes. 



tbersi tes = orestes \ ar. thersites. 



tener = toner. 



neglectus = tener. 



The genus Haittia and species, Harttia matthewi, is proposed for a 

 small patelloid form of gasteropod. Mr. Matthew was requested to give 

 names to the new species, other than the preceding, aud he proposed 

 Liugula f dawsoni (p. 15), Hyolithes danianus (p. 20.), Hyolithes micmac
