6 GENERAL EEMAEKS. 



Report on the Florida Reefs by Louis Agassiz was published by his son, the special interest 

 of which, for our present purpose, centres in the three excellent plates of M. palmata, 

 M. cervicornis, and M. prolifera. 



In the ' Marine Fauna of Mauritius and Seychelles/ by Mobius, Richters, and v. Martens, 

 seyen species of Madrepora are recorded by Mobius from Mauritius, which were identified by 

 Haacke ; six of the species also occur in the Red Sea. S. O. Ridley, in a paper on the Coral 

 Fauna of Ceylon (1883), records two species of Madrepora. H. 0. Forbes gives, in his 

 ' Naturalist's Wanderings in the Eastern Archipelago' (1885), a list of Corals collected in ^ 

 the Keeling Islands, which were determined by Ridley and Quelch, in which two species of 

 Madrepora are recorded, one of which is named M. orbipora, Dana, var. ; but no species 

 was described by Dana under that name ; the specific name intended is probably cribripora. 

 The ' Challenger ' Report on Coral Reefs by Quelch appeared in 1886, and in it fifty 

 species of Madrepora are recorded, eleven of which are new. In the same year Duncan 

 described a collection of Corals from the Mergui Archipelago, which included eight species 

 of Madrepora, all of which are referred to known species. 



In 1888 Rathbun published a catalogue of the species of Madrepora in the United-States 

 National Museum. The list includes 59 species in all j the type specimens of 48 of the new 

 species described by Dana and also 6 of VerrilFs are in the Collection. The types of the 

 remaining species of Madrepora described by Dana appear to have been lost, excepting in the 

 rare instances (e. g. M. digitifera) where the species were described from specimens already 

 in the collection of other institutions. This collection also contains the type of M. secale, 

 Studer (= M. plantaginea, Dana, non Lamk.). 



Ortmann has published two important descriptive papers in which numerous species of 

 Madrepora are recorded. The first, published in 1888, is a list of the collection of Corals in 

 the Strassburg Museum. In this paper 44 species of Madrepora are enumerated, only one of 

 which is described as new, but in the case of 8 others the reference to known species is made 

 with considerable doubt. The second paper is devoted to a description of a collection of 

 Corals made by Haeckel in Ceylon, the types of which are in Jena; 37 species are here 

 recorded, 5 of which are described as new to science. In Faurot's ' Report on the Red 

 Sea Mission,' published in 1888, 4 species of Madrepora are recorded, 3 from the Gulf of 

 Aden and 1 from Kamaram Island. 



In 1890 Bassett-Smith described a collection of Corals from the China Sea (Macclesfield 

 and Tizard Banks), In this paper 30 species of Madrepora are enumerated, 4 of which are 

 described as new, but a fifth, which is considered new, is not named. An interesting feature 

 in this collection is the fact that all the new species were obtained at depths between 23 and 

 30 fathoms. In the same year Thurston published a paper on the Fisheries and Marine 

 Fauna of the Gulf of Manaar, in which the occurrence of 3 species of Madrepora is recorded.

Since the systematic portion of this work was completed, a paper by Dr. Rehberg, " Ueber 

 und wenig bekannte Korallen," has come into my hands ; it was published in November
