T. H. Huxley has compared the number and position of ihe gills of 
the Astacidce (infra) with those in other Crustacea. In the majority of 
the Macrura the number of the podobranchiae is diminished, in Peneus^ 
Gehia^ and Callianassa they are entirely wanting ; the nine gills of the 
regular BracJiyura consist of a podobranchia on the second and third 
maxillipeds, an anterior arthrobranchia on the second maxilliped, two 
arthrobrauchiae on the third maxilliped and on the first thoracic foot, 
finally a pleurobranchia on the second and third thoracic feet. On 
account of these differences he distinguishes three types : — 
1. CaridomoiyJia, characterized by the predominance of the pleuro- 
branchias and the diminution in number and importance of the 
arthrobranchiae and podobranchiae. This comprises the Carides, 
excluding the Peneidce. 
2. Anomomorpha^ distinguished by the almost complete abortion of the 
podobranchiae and the presence of ten arthrobranchiae attached in pairs 
to the middle thoracic segments ; corresponding nearly with Haan’s 
Anomala, and comprising Poi'cellana, Galatea^ Lithodes^ Pagurus, 
Remipes^ Callianassa, and Gebia. 
3. Carcinomorpha, characterized by only two podobranchiae, viz., on the 
second and third maxilliped, comprising the true Brachyura, and 
Ranina, Homola, and Dromia. 
' All these are Phyllohranchiata, having lamellar gills, whereas another and 
more lower division is formed by those in which the gills consist of a stem 
beset with numerous cylindricaL filaments ; these ^re called Tricho- 
branchiata and comprise the Peneidce, EuphausidcB, Thalassinidoe, 
Homaridce, Potamobiidce, Parastacidce (infra), and Palinuridce. The 
last-named two groups, being devoid of male appendages in the first 
abdominal segment, and agreeing in the disposition of the gills, are 
termed Astyla, distinguished from the Abranchiata {Mysiclce'),ihe rest of 
the Trichobranchiata and the Phyllobranchiata, which are all “ Stylo- 
pliora” P. Z. S. 1878, pp. 776-785. [These divisions seem rather artificial.]
