lowing are ornitlioiogical : (i) 'Description of an appurenllj- New Spe- 

 cies of Warbler from Jamaica' (No. i, p. 30, pi. iii, fig. i,head). Tiiis is 

 named Dundrceca ignota, and is said to bear a general resemblance to D. 

 fulmariim. It is based on a single specimen in the Museum of the Insti- 

 tute of Jamaica, at Kingston, Jamaica, where the type remains, "labelled 

 'liamstead, St. Andrews, April 4th, '79. J. Goodlet.' " 



(2) 'The Sterno-trachealis as a Vocal Muscle' {ibid., pp. 35-37, pi- 

 iii, fig. 2-14). This muscle is claimed to be a true vocal muscle, and 

 hence Mr. Maynard assigns six pairs of vocal muscles to the Oscines. 



(3) 'Notes on Some Jamaican Birds' {ibid., pp. 39, 40). Notes on five 

 species. Rallus coryi is recorded from Jamaica, and Helinaia sruaiii- 

 .<o«// is judged to be "a quite common winter bird in Jamaica," from the 

 number of skins in the Museutn of the Institute of Jamaica. 



(4) 'Description of a supposed New Species of Gannet' {ibid., pp. 40- 

 48, and No. 2, pp. 51-57, pi. v, fig. i and 2, heads of adult and voung). 

 This, named Snla coryi, is the Sula cyanops of Cory from Cayman Brae 

 and Little Cayman {cf. Auk, VI, 1SS9, pp. 31, 32). A detailed descrip- 

 tion is given of the various phases of plumage, from the nestling to the 

 adult; also a very full account of the habits of the species. At least 

 10,000 of these Gannets were estimated to be breeding "in the gannetry 

 at Little Cayman." It has the form and size of the Red-faced Gannet 

 {Sula piscator^, but differs from it in having the tail wholly white. 



(5) 'The Vocal Organs of the American Bittern, Botanrus lentigino- 

 sus' (No. 2, pp. 59-68, pi. vi, and 6 figs, in text). This is an attempt to 

 explain, on anatomical grounds, the production of the singular pumping 

 sounds this species emits. By a singular coincidence, Mr. Maynard's 

 studies appear to have been based on the very individual which formed 

 the basis of Mr. Bradford Torrey's paper on this species in 'The Auk' 

 (VI, 1S89, pp. 1-8) ; they tend to confirm Mr. Torrey's hypothesis there 

 given. 



(6) 'Notes on the Anatomical Structure of the Crowned Crane 

 {ibid., pp. 80-82). 



(7) 'On the probable Evolution of the Totipalmate Birds, Pelicans, 

 Gannets, etc' {ibid., pp. 82-8S). This is a paper of considerable inter- 

 est, but not easy to summarize. The Pelicans are considered to be the cen- 

 tral and oldest type, the Tropic Birds and the Frigate Birds the most 

 specialized. The American Gannets are believed to be recent oft'shoots 

 from two stocks, represented by Sula sula and .S. cyanops. 



(8) 'The Sound-producing Organs of Birds' (No. 3, pp. 101-106, figs. 

 16-19, and No. 4, pp. 164-167, figs. 40, 41). The species particularly con- 

 sidered are the Bohemian Waxwing, the American Woodcock, the Even- 

 ing Grosbeak, the American Barn Owl, the Ani, and the American 

 Flamingo. 



(9) 'Notes on the Anatomical Structure of three Species of Gannets' 

 {ibid., pp. 116-123, figs. 21-27, ^n<^ ^o- 4' PP- I5i-i53> ^'il^- 36-39). These 

 are Sula sula, S. coryi, and 5. bassana.
