thetidis, Lepidotrigla modesta, Parapercis ocularis, Histiopterus farnelli, 
and Paralichthys tenuirastrum. A new name, var. elevatus, is pro- 
posed for the Australian representative of Macrorhamphosus scolopax. 
Two new genera, Paratrachichtys (trailli) and Pterygotrigla (polyom- 
mata, in place of Hoplonotus, preoccupied), are defined. 
_ Perhaps the most interesting of the new forms is Sebastodes thetidis. 
That genus, now known to be represented by about fifty species off 
the coast of California and a dozen more in Japan, and a few off 
Chili, has its range thus extended southward to Australia. The new 
species is one of the extremes of the type, somewhat allied to S. nigro- 
cinctus, but still more spinous about the head. In the present sys- 
tem it would be the type of a distinct subgenus, or possibly genus, 
standing at the very opposite extreme of the series from Sebastodes 
paucispinis, the original type of the genus. 
The nomenclature and sequence adopted by Mr. Waite are thor- 
oughly modern and in accordance with the law of priority. We may 
perhaps question the identity of the Australian horse mackerel with 
Sarda chilensis of Chili, or of the kingfish with Lenola /a/audi of 
Brazil. 'These identifications have been accepted by authors, the 
present writer among the number, but it seems better not to regard 
à species as cosmopolitan until actual comparison has shown it to 
be so. In most cases of this kind comparison of adequate material 
will show specific difference. 
It is to be hoped that this very acceptable piece of work will be 
followed by many others until the natural history of Australia is 
thoroughly known. D. $ J. 
Smitt on Lycodes. — In Annals and Magazine of Natural History, 
Professor F. A. Smitt, of Stockholm, has a brief review of the spe- 
cies of Lycodes of the North Atlantic. He maintains that all speci- 
mens known to him are referable to four species. Zycodes reticulatus, 
vahlii, sarsii, and muræna. Lycodes perspicillum (L. rossii), he thinks, 
is the young of Z. reticulatus, which is probably correct. Zycodes 
rigidus is a “ mixture of sterile or deformed specimens” of vahlii 
and reticulatus. Zycodes gracilis is a northern variety of Z. vahiii, 
with the head shorter (less than 22 per cent of total length ; more 
than 22 per cent in typical vahlii). He suggests that Lycodes 
murcna is probably “a local or evolutional form of Zycodes sarsii.” 
But that is about all that one could claim for any of the species in a 
group like Lycodes, in which the species are all closely related and 
vary much with conditions.
