Bemserkninger. Nservserende anselige Crangonide er 
allerede i Aaret 1815 beskrevet at' Tilesius efter Exemplarer 
fra Kamtscbatka, men af ham lcnn anseet for en Yarietet 
af <len af Pbipps forst omtalte Asfacus ( Crcmgon ) boreas. 
24 Aar derefter blev sannne Form after undersogt af Owen 
og beskrevet i “Zool. of Beechey’s Voyage” som en ny 
Art under Bensevnelsen Crcmgon sahbrosus. Senere har 
denne Form, saa vidt mig bekjendt, ikke vseret noiere om- 
talt. 1 
Arten slutter sig saavel i sin ydre Habitus som i den 
anatomiske Bygning meget nser til Sclerocrangon boreas 
(Phipps), men riser dog tilstraskkelige Afvigelser til at dens 
Artsforskjel nma sadtes udenfor al Tvivl. Af disse Afvi- 
gelser kan fremhseves: Pamlehornets meget eiendonunelige 
Form, den staerke IMvikling af saavel Kjolene som de torn- 
formige Fremspring paa Legemet, endidig den characteri- 
stiske Bevsebning af Bagkropssegmenternes Epimerer. 
I min Prodromus har jeg for denne Art benyttet det 
af Kinahan foreslaaede Slmgtsnavn Cheraphilus. Dette an- 
ser jeg nu for mindre rigtigt. Yistnok henforer Kinahan 
ogsaa Crangon hrreas til denne Sltegt ; men da han selv 
ikke. synes at have undersogt liin Art. vil det vistnok vsere 
mere correct at indskraenke Slaegten Cheraphilus, om denne 
godkjendes, til de af naevnte Forsker selv noiere beskrevne 
Arter, eller en begraendset Del af disse. 
Beskrivelse. Legemet er (se PI. 2, Fig. 1 og 2) af 
plump og undersaetsig Form, med Hoide- og Bredediame- 
teren omtrent ens. 
Integumenterne er haarde og staerkt incrusterede samt

vidste jeg ikke dengang jeg skrev min Prodromus, at ncervserende 
Form allerede tidligere var beskrevet. og opfdrte den derfor som en 
ny Art. Jeg har imidlertid senere overbevist mig om, at deni Virke- 
liglieden er identisk ined Owens Art, livorfor den selvf0lgeligt maa 
beholde det addre af denne Forsker anvendte Artsnavn. 
arcuate, with 3 distinct longitudinal carinae, of which the 
median carina rises into 3 apophyses, exceedingly large, 
compressed, comparatively uniform in development, and bent 
anteriorly, the lateral carinte dividing each into 2 similar 
processes. Antero-lateral spines remarkably large, triangular- 
acute, and turning obliquely outward. Rostrum compara- 
tively large, broad at the base, but from thence compressed, 
— downward almost securiform-dilated, with the extremity 
produced into a. long and acute point turning obliquely 
upward. Abdominal segments carinated along the middle; 
' the two anterior, above, with a high, compressed process: 
last segment with 2 parallel carina?. Epimera with denti- 
form projections on the margins. Telson hollowed out 
above longitudinally, with 3 lateral teeth, extremity triang- 
ular-acute. Colour brownish-red, with darker shadings. 
Length reaching 130 mm .

Remarks. — This large Crangonidian was described 
as early as the year 1815, by Tilesius, from specimens 
collected at Kamtscbatka, but regarded by that author 
merely as a variety of the form Astacus ( Crcmgon ) boreas, 
first recorded by Phipps. Four and twenty years later, 
this animal was again examined, by Owen, and described, 
in “Zool. of Beechey’s Voyage,” as a new species, under the 
name of Crangon salebrosus. Subsequently, to the best of 
my knowledge, a more detailed- description has not been 
given of the form. 1 
The species approximates very closely both in its 
habitus and anatomical structure Sclerocrangon boreas (Pbipps). 
but exhibits however sufficient characteristic divergencies to 
place beyond doubt its specific distinctness. Of these diver- 
gencies may be mentioned: — The very peculiar form of 
the rostrum, the remarkable development alike of the carina; 
and of the spiniform projections on the body, and finally 
the characteristic armature of the epimera of the abdominal 
segments. 
In my Prodromus I have adopted for the present 
species the generic name Cheraphilus, suggested by Kinahan. 
This appellation I do not now, however, regard as strictly 
correct. True, Kinahan also refers Crangon boreas to the 
same genus; but apparently not having himself examined the 
species, it will, I opine, be safest to comprise in Cheraphilus, 
provided that genus be accepted, such species only as the 
aforesaid naturalist has described more in detail, or a 
limited number thereof. 
Description. — The body (see PI II, figs. 1, 2) 
clumsy and thickset in form, height and breadth about 
equal. 
The integuments are hard and thickly incrusted, and 
1 Since Owen’s above-cited Memoir is not to be had in the 
Library of the Christiania University. I was not aware, when writing 
my Prodromus, that the form in question had previously been de- 
scribed, for which reason I spoke of it as a new species. I have sub- 
sequently, however, been convinced that the animal is identical with 
Owen’s species, and must therefore of course retain the original specific 
appellation assigned to it hv that naturalist.
