species, resembling it enough to be mistaken for it. At 

 least I must confess that I had regarded specimens sent me 

 from time to time by Mr. Bateman, Mr. Barker, Mr. Lod- 

 diges, and others, as mere varieties of Notylia punctata. 

 I am however now satisfied, from the examination of speci- 

 mens placed in my hands by Mr. Loddiges, that the supposed 

 varieties constitute at least five well marked species ; all 

 agreeing in habit, but differing in the form of their labellum, 

 &c. in the size of their flowers, in smell, and in the length 

 of their racemes. I hope the specific characters now given 

 will prevent confusion in future. 



The true Notylia punctata has whiter flowers than any 

 of the others, with a short flexuose raceme, and obtuse 

 sepals, petals, and labellum, at the base of the latter of which 

 is an elevated callus. 



167. NOTYLIA incurva. 



N. incurva ; labello unguiculato cordato-ovato acuminata sub apice carinato basi 

 ecalloso margine reflexo, sepalis lateralibus apice rectis petalisque lanceolatis 

 acutis columna recurva. 



Of this the flowers are larger than any of the others, a 

 pale straw colour, with two or three yellow spots near the 

 base of each petal ; the divisions are lanceolate and acute, 

 not acuminate ; the ends of the lateral sepals are straight, 

 not reflexed ; and the column is rather abruptly curved 

 inwards towards the dorsal sepal. Messrs. Loddiges obtained 

 it from Trinidad. 



168. NOTYLIA Barkeri. 



N. Barkeri ; labello unguiculato cordato-ovato basi calloso margine subreflexo, 

 sepalis lateralibus apice refiexis petalisque lineari-lanceolatis acutis, columna 

 recurva. 



Very like the last, but the flowers are smaller and 

 yellower, the labellum is not acute, and it has a distinct 

 elevated callosity at the base. Mexico, Mr. Barker, 1837. 



169. NOTYLIA tenuis. 



N. tenuis; labello unguiculato cordato-ovato setaceo-acuminato basi ecalloso 

 margine reflexo, sepalo supremo falcato inflexo lateralibus apice revolutis 

 petalisque linearibus acuminatis, columna recta.
