Studer (37) describes as new: — 
Amblypneustes grossularia, p. 873, pi. i. fig. 6, New Zealand (perhaps 
the young of a described form). 
Catopygus loveni, p. 878, pi. i. figs. 1-1 d, South of Cape of Good Hope. 
Spatangus (^Loncophorus) interruptus, p. 880, pi. ii. figs. 2-2 b, West 
Australia. 
Hemiaster fiorigerus, p. 882, pi. ii. figs. 3-3 c. 
Schizaster capensis, p. 884, pi. ii. fig. 4. 
He also figures the lately described Schleinitzia crenularis and Astropyga 
elastica^ and pedicellariae of Arbacia dufresni, A. alternans, Echinus 
margaritaceus, and E. diadema. 
Stomopneustes atropurpurea (P sp. n.), J. E. T. Woods, P. Linn. Soc. 
N. S. W. V. p. 198. 
Bell (3) defines Palonolampas^ g. n., as A petalostichous Echinid, in 
which the completely parallel ambulacral pores remain paired as far as 
the ambitus, and in which the tendency to the shortening of one of the two 
sets is only very slightly indicated in the antero-lateral pair ; the outer 
row of each pair of pores is regularly distributed from the apical area to 
the actinostome. Bourrelets feebly developed. Anus elongated trans- 
versely, infra-marginal. Four genital pores ; ocular pores large. 
Tubercles all primary, and equally distributed over the test. Test not 
very high. Apical system and actinostome a little in front of the true 
centre of the test.’^ P. crassa, sp. u. ' 
Martin (29) describes as new : — 
Pleurechinus javanus and Laganum multiforme ; aud points out that in 
his opinion : — 
Cidaris myxta, Herklots, = Phyllacanthus baculosa,Ag. 
Temnopleurus arcolatus, Herk., and T. coclatus^ Herk., are varieties of 
T. toreumaticus, Ag. 
Heliocidaris variolosa^ Herk., = Stomopneustes variolaris, Ag. 
Scutella decagona, Herk., = Pcronella dccagonalis, Ag. 
Clypeaster latus, Herk., = C. humilis, Ag. 
Clypeaster tumescens, Herk., = Echinanthus testudinarius, Gray. 
Echinolampas subangulata (Herk.) = (?) E. oviformis, Ag. 
Brissopsis latior, Herk., = Verberkia dubia, V. Fritsch (?) = B. 
luzonica, Ag. 
Pericosmus granulatus, H., == P. rotundatus, = P. planulatus. — P. 
distinctus, all species of HerkloVs. 
Eupatdgiis magnust Herk., is a Breynia, and is closely allied to B. 
australasice, Gray. 
Spatangus prcelongus, Herk., = S. affinis, H., = Maretia planulata, 
Gray. Sp. pulchellus, Herk., is probably a Maretia. 
Our present knowledge of the Echini of Java shows that the recent
