but we are convinced that it is possible, by 

 consultation and conference, to secure a 

 cooperation thus limited which will prove 

 beneficial to industrial education in gen- 

 eral, as well as to the particular work of 

 both institutions. By the more frequent 

 interchange of instructors, by allowing to 

 the advanced students of each institution 

 such privileges of instruction in the other 

 as may be practicable, by the common use 

 of valuable apparatus, by the participation 

 in University and Institute seminars of 

 instructors and students of both institu- 

 tions, by giving advanced courses of lec- 

 tures to the combined classes of both insti- 

 tutions; perhaps by mutual agreement 

 from time to time to relegate certain 

 branches of instruction to one of the two ; 

 by carrying out together advanced engi- 

 neering researches and tests,— by these, 

 and by various other ways that will suggest 

 themselves, much may be accomplished in 

 harmonious effort which should be highly 

 beneficial to both the University and the 

 Institute. This development, however, 

 must be a growth. It can not be forced, 

 as the proposed agreement would attempt 

 to force it, for it is in the nature of con- 

 tinuous experiment, presenting problems 

 for the solution of which no data exist.

 Madreporaria, Parts III. and IV. By J. 

 Stanley Gardiner, M.A., etc. (From ' The 

 Fauna and Geography of the Maldive 

 and Laccadive Archipelagoes,' Vol. IL, 

 Supplement L, pp. 933-957, pis. LXXXIX- 

 XCIII.) 



The first installment of Mr. Gardiner's re- 

 port on the Madreporaria from the Maldive 

 and Laccadive Archipelagoes has already been 

 reviewed in the columns of this journal.* 

 The second installment, which has just been 

 received, contains an account of the Fungida 

 and Turbinolidse.

///. Fungida. — 548 specimens, besides a 

 number of young forms and fragments, were 

 obtained. These are divided into 27 species 

 and 2 varieties, representing 15 genera; 

 against 24 species and 9 genera reported by 

 Klunzinger from the Ked Sea, and 15 species 

 and 7 genera found by the author in the 

 Pacific. 



The following is a list of the genera with 

 the number of species referred to each,- and 

 the names of the forms considered new : 

 PsammoseriSj 1; Siderastrea, 4, S. maldi- 

 vensis, nov. ; Agaricia, 1, A. ponderosa, nov., 

 + var. minikoiensis, nov.; Fungia, 3; Podo- 

 hacia, 1; Halomitra, 1; Herpetolitha, 1, H. 

 simplex, nov.; Cycloseris, 2; Diaseris, 1; 

 Pavonia, 1; Leptoseris, 3, L. incrustans, nov.; 

 Echinophyllia, 1; Pachyseris, 1; Coscinaroea, 

 2, C. donnani, nov.; Psammocora, 4; P. di- 

 varicata, nov. 



Mr. Gardiner does not follow von Maren- 

 zeller in referring Stephanoseris to the syn- 

 onymy of Heterocyathiis and Psammoseris to 

 that of Heteropsammia, but combines Ste- 

 phanoseris and Psammoseris under the latter 

 name. He goes further and puts the type 

 species of Psammoseris (P. hemispherica) in 

 the synonymy of the type species of Stephano- 

 seris, which was originally described as 

 Heterocyathus roiosswanus. 



I somewhat doubt the correctness of the 

 generic determination of Siderastrea clava, S. 

 lilacea and S. maldivensis. Mr. Gardiner 

 calls attention to these ' having in their sur- 

 face parts the thecas of neighboring calices 

 quite separate from one another, joined to- 

 gether only by costse, instead of fused to- 

 gether into a single dividing wall.' This dif- 

 ference did not escape his attention. 



Mr. Gardiner himself doubts his Agaricia 

 ponderosa really being an Agaricia. I feel 

 rather confident that it is not an Agaricia. 

 The type species of the genus is A. undata 

 (Ell. & Sol.) Lamk; the type specimen is in 

 the Hunterian Museum, Glasgow, where I 

 have seen it and Professor J. Graham Kerr has 

 kindly sent me photographs. The genus can 

 be briefly characterized as follows : Corallum 

 compound, thin, foliaceous. Common wall 

 imperforate, naked, finely striate; no differen-
