or varieties." (Pr. Bo«t. Soc. Xat. Hist., 180G, p. 248.) In the paper in 



wbicli we find the above words he applied the following triuoniinals : 



Certhiola Jfaveola Ya,r. portoricensis. 



FringiUa zena Linn. 1758 Var. portoricensis. 



Icterus dominicensis Var. portoricensis. 



Icterus dominieensis Var. hypomeJas Dubns. 



tSaurothera vieiUoti Var. rufescens. 



In his additional ''List of Birds seen at the Bahamas" (Pr. Bost. Soc. 

 Nat. Hist., xi, pp. 63 seqv.) he nses: 

 Psittacus coUarius var. hakamensis. 

 Tyrannula stulida var. Incaysiensls. 

 Mimus polyylottus var. hakamensis. 



And in a paper on Birds of St. Douiiugo (1. c, pp. 89, seqv.), the fol- 

 lowing triuoniinals: 

 Tyrannula stolida var. dominicensis. 

 Tyrannula carribtca var. liispaniolensis. 

 Turdus ardosiaceus var. portoricensis. 

 Fringilla zena var. marchii. 

 Hirundo euchrysea, var. dominicensis. 



So great was the power of the example, that even at that early date 

 few oi' the ornithologists could resist using — although more or less spo- 

 radically — trinominals, an eft'ort especially visible in the youuger gen- 

 eration, which may titly be termed " Baird's school." It is unnecessary 



in the present paper to go into details, but a few instances may be men- 

 tioned. 



In 18GG Dr. Cones, in a paper on " the Ornithology of Arizona Terri- 

 tory" (Pr. Phil. Acad., 18GG), instituted several trinominals: 



Chrysomitris [Pseudomitris) mexicanus. A. var. mexicanns. B. var. 

 columhianus. C. var. arizona. 



Mr. Eidgway (Pr. Phil. Acad., 1870), enumerates the following Amer- 

 ican forms of 

 Tinnunculus sparverius 



var. sparverius. 



var. austral is. 



var. isahellinus. 



var. dominicensis. 



var. ? cinnamominus. 

 In fact, trinominals were in the air infecting all, so that we find them 

 where least expected. They make their way into Mr. Lawrence's pa- 

 pers on birds from South and Central America, Mexico, and the islands 

 of Tres Marias and Socorro (1871), partly as manuscript names of Pro- 

 fessor Baird, partly without his name appended, for instance : 

 Conurus holochloriis var. brecipes Baird, M. S. 

 Buteo borealis var. montana Nutt. 

 Falco peregrinus vsir. nigriceps Cass. 

 Uadrosiomus aglaice var. affinis (Elliot). 

 Haliplana fuliginosa var. crissalis Baird, M. S.
