A MEDLEY OF ANIMALS 403 
brought together, and, as it were, jumbled up into a sort 
of compound animal, so that when the Pagurid devours 
a shrimp, its gastronomic exertions are supplying food 
through the remnants of a shapeless Cirripede to a degraded 
Isopod. This remarkable arrangement on the body of a 
hermit-crab, itself occupying the shell of a departed mol- 
lusc, must be regarded as the result of special creation by 
those who still uphold the venerable doctrine of the fixity 
of species. What a gasp an intelligent mind must give at 
swallowing such an explanation ! 
Cryptoniscus paguri, Fraisse, 1878, was found on Pelto- 
gaster Fodriquezii, Fraisse, on Clibanarius misanthropus, 
Risso, at Mahon in Minorca. It is described as flat and 
worm-like, much resembling the preceding species. 
Cryptoniscus larveeformis, Giard, 1874, on Sacculina 
carci. 
Danalia, Giard, 1887, was substituted for part of 
Zeuxo, Kossmann, 1872, preoccupied. 
Danalia curvata (Fraisse), 1878, on Sacculina neglecta, 
Fraisse, from the Bay of Naples, is said to be round and 
rolled together, very like the Cabirops lernwodiscoides. of 
Kossmann. Dr. Fraisse says that it is either a simple 
parasite on the Sacculina, or placed beside it on the crab 
Inachus scorpio, Fabricius, but that in any case it has to 
draw its nourishment from the roots of the Sacculina. 
Danalia Lobiancoi, Giard and Bonnier, 1890, on Portu- 
nascus corrugatus, Giard. 
Danalia Dohrni, Giard, 1887, on Grapsisaccus Benedeni, 
Kossmann. The Zeuxo longicollis of Kossmann, 1880, was 
found on the pleon of Chlorodius (Leptodius) exaratus, 
Milne-Edwards, in company with but remote from a Sac- 
culina. 
Tnriopsis, Max Schultze, 1859, was substituted for 
Tiriope, Rathke, 1845, preoccupied. 
Tnriopsis pyymeea (Rathke), 1843, on Peltogaster pagurt, 
Rathke. The first antennz have a very thick bundle of 
hairs attached to the outer side of the basal joint in the 
male. 
Tiriopsis monophthalma (Fraisse), 1878, on Peltogaster
