ADDITIONS TO THE BIBLIOGRAPHY OF WEST INDIAN TERTIARY 

 DECAPODA. 



1863-64. Edwards, Alphokse Milxe. Monographie des Criistaces Fossilea de la 

 Famine des Canceriens. [Part 2], Aun. Sci. Nat., ser. 4, Zool., vol. 20, 

 Paris, 1863, pp. 273-324, pis. 5-12; [Part S], Ann. Sci, Nat., ser. 5, Zool , 

 vol. 1, Paris, 1864, pp. 31-88, pis. 3-9. 

 This monograph, which appeared in four parts, is devoted to Old World species 

 with one exception, Lobonotus sculptus A. Milne Edwards, from San Domingo. This 

 is figured in vol. 20, 1863, pi. 10, figs. 1, la, 16, and described in vol. 1, 1864, p. 40. 

 It is the same as my Archmopilumnus caelatus (Publ. No. 291, Carnegie Inst., Wash- 

 ington, 1919, p. 177, pi. 6, figs. 6 and 7; pi. 7, figs. 10-13; pi. 8, figs. 4-7). The genus 

 Archaeopilmnnus is, therefore, a synonym of Lobonotus. This genus appears to me 

 nearer the Pilumninae than the Xanthinae where Milne Edwards placed it; the 

 presence or absence of palatal ridges defining the efferent Itranchial channels is still 

 to be determined . 



1912. Maury, Carlotta Joaqtjima. A contribution to the Paleontology of Trini- 

 dad. Journ. Acad. Nat. Sci. Philadelphia, ser. 2, vol. 15, pp. 25-112, pis.

One crustacean is ILsted and figured, Ranina pori/era Woodward (p. 106, pi. 13, fig. 

 23), from Farallon Rock or Johnson's Island, near San Fernando, Trinidad, in the 

 Gulf of Paria, lower Oligocene.
