1878, Garrod, a. H. Ou tlie Systematic Position of tlie Momotidip. < P. Z. S.. Jan., 

 15, 1878, pp. 100-102, figg. A, B. 



Cf. P. Z. S., 1874, p. 123 : errors there made here corrected. Colic coeca absent ; minute tuft 

 on oil-gland, or none. Such being the case, Momotidce must be placed with the Pidformee 

 as defined by Garrod, instead of with Pasneriformes. Momotidce scarcely separable as a 

 family from Todidce. A pterylographic peculiarity favors the reference of the family to Fid- 

 formes. Syrinx of Momatus lessoni figured, 2 views.
