blooded vertebrates generally, and of those three elasses speeially. 
In conclusion he admits the possibility that future discoveries 
may prove a more intimate relation between the three types of 
cold-blooded vertebrates than is apparent at present. 
DIPNOI. 
Lcpidosiren annectem. M. Paulson has examined the structure of its epider- 
mis. Bull. Ac. Sc. St. r^tersb. 18G5, viii. pp. 141-145, with a plate, 
ACANTIIOPTEBTGII. 
Prof. Kner observes that the term '^ctenoid scales^’ is too 
indefinite, and proposes the name squam€B ctenoidecR monosticha* 
for those the margin of which only is serrated, and that of 
squam (2 cten. pleiosticJus for the scales the spines of which form 
several series covering a part of the surface of the scales.

Lahrax. Prof. Peters describes a new species, L. sehcenleinii^ from Celebes, 
and confirms Dr. Steindachner’s opinion that Lahrax elongatus (gen. Picen- 
trarchus, Gill) is identical with '‘L. diacantMs, Monatsber. Akad. AViss.

Ccn^opomus, The Cu^an species mentioned by Cuvier and Valenciennes

Wiss. Berl. 1865, p. 100. 
Serranus, Prof. Peters has examined a part of the Blochian 
types of Serranus, and rectified the synonymy of the following 
species (Monatsber. Ak. Wiss. Berl. 1865, pp. 99-111) ; — 
1. Holocentrus maroccanus (Bl. Schn.) is a good species, and afterwards 
described by Valenciennes as Serr. papilio7iac(ms (p. 99). 
4 2. Jlolocenlrm viresce7is (Bl.) is not identical with S. cahriUa, but some 
species of A7itJnas ; it is described (p. 100). 
>1 3. JIolocent7'us arge7itmus (Bl.) = S. cah7'illa, which has as frequently seven 
jts eight anal rays (p. 101). 
^4 4. Holocentrus 07igus (BL), not —S. diclwoptei'us (Cuv. & Val.), from 
Brazil, but —8. hatame7isis (Blkr.) (p. 102). 
• 5. Holocc7it7'us aiu'atus (BL) =<S'. quratus (Cuv.). Prof, peters is inclined 
to regard this specie^, S. oiiataliU,^. pu7xctatm (Poey), and /S', guatimre as 
varieties of colour (p. 103), i
