 Indem wir für alles Weitere auf das Werk selbst verweisen, 

 fügen wir nachfolgend nur noch die Diagnosen der zwei neuen Ge- 

 nera hinzu: 



Honiolampas B. gen. Is intei^mediate between Cardiaster and 

 Holaster. It has, like those genera, anibulacra flush with the test, 

 but, unlike Holaster, has a well developed anal and subanal fa- 

 sciola, while it wants the lateral fasciola of Cardiaster. The ambula- 

 cral pores form no petals ; they extend as simple pores between 

 the ambulacral plates from the phyllodes to the apex. The actinal 

 surface is flat; the actinostonie is pentagoual, not bilabial with well 

 developed phyllodes, but without trace of bourrelets — a strong con- 

 necting link between the Cassidulidae and Spatangoids proper. The 

 compactness of the apical systeni of this genus is in marked contrast 

 with its structurc in allied genera, such as Cardiaster and Holaater. 

 The general outline of the test resembles Maretia, but is some- 

 what more elongate. It is closely allied to Platybrissus, but the pres- 

 ence of a subanal fasciola as well , as a slight anterior groove 

 readely distinguisli the two genera in additiou of the presence of a 

 rudimentary rosette in Platybrissus, wanting to this genus. (P. 347.) 

 Uliyncliobrissus n. gen. Test thin; outline from above dia- 

 mont-shaped; vertex posterior; lateral ambulacra petaloid. Odd. ante- 

 rior ambiilacrum flush witli the test. Peripetalous fasciola existing with 

 independent anal and subanal fasciolae. Anal fasciola forming a 

 closed anal area. Tubercles remarkable for the great development of 

 the flat raised scrobicular area. Spines of abactinal surface short, 

 silk-like, curved; on the actinal surface long, curved. Posterior late- 

 ral ambulacra passing gradually into the actiual surface, without 

 forming a marked edge of the test in the posterior extremity. The 

 edge of the test is welldefined in the anterior actinal extremity. (P. 590.)
