Geographical Distribution and Local Lists. 
Mr. HartFs collection of Echinoderms, made in 1867, on the 
coral-reefs of the coast of Brazil, was found to contain many 
species yet undescribed as occurring on that coast. Prof. Verrill 
(/. c.) publishes the following list of species ; — 
Antedon diibmii (?), Bolsche j Ophiomyxa Jlaccida, Liit. ; Ophiactis krehsii, 
Liit. ; Ophionereis reticulata^ Say j Ophiothrix violacea, M. & T. j Ophiolepis 
paucispina, M. & T. ; Ophiura cinerea, Lym. j Oreaster gigas (Linn.) j Linckia 
ornithopiis, Liit.; Echinaster crassi5/>ma, Verrill ; Asterias atlanfica^ Verrill; 
Lytechinus variegatus^ A. Agas. ; Echinometra michelini, Desor, ; Encope 
emarginatus (Leske) ; Thy one braziliensis, Verrill ; Chirodota rotiferumf 
Stimp. 
Prof. Verrill (/. c.) enumerates the following as found at La 
Paz, Lower California : — 
Ophiactis mrescens, Liit. ; Lmckia unifascialis, Gray ; Nidorellia armata, 
Gray; Amphiaster insignisj gn. et spec, no v., Verrill; Oreaster occidentalism 
Verrill; Cidaris thotiarsiim Y sX. ) Echinometra van-hruntij A. Ag. ; Tripneu- 
stes depressus, A. Ag. ; Encope grandis, Ag. ; Brissus ohesus, Verrill. 
Anatomy and Physiology. 
The fourth part of Semper^s work, pp. 101-177, is completely 
taken up with notes on the anatomy of the subclass of the Ho- 
lothurioids. It would be impossible here to give ever so slight 
an epitome of these seventy- six pages ; but it may be useful to 
give the headings of the chapters in this section of this work. 
1. On the alimentary system and accessory apparatus. 2. On 
the vascular system. [We must mention here the strange amoe- 
boid-like corpuscles met with by Semper in the circulatory 
fluid (Schleimzellen) ; they are figured on Taf. xxxiii. figs. 10, 
12, 14. It is of great interest to compare these with the forms 
referred to and figured by Claparede, vide antea, p. 545.] 3. The 
water- vascular system. 4. The respiratory organs of the Aspi- 
dochirotae and the organ of Cuvier. 5. The organs of genera- 
tion. 6. The nervous system. 7. The muscular and locomotive 
system. 8. The inner skeleton. 9. The skin. [In a footnote 
Dr. Semper states that Prof. Grube mentioned to him that he 
has a sea-urchin from the China Sea with a quite soft skin : see 
special part, under Diademidae.] Some chemical researches, by 
Dr. llilger, are also given.
