General Morphology. 
J. E. V. Boas publishes a paper on the systematic relations of the 
Malacostraca , based chiefly on his own researches on the structure of the 
dermal skeleton ; he thinks that all Malacostraca can be derived from the 
Phyllopoda, and may be grouped into the following 7 orders : Euphausi- 
acea , Mysidacea, including Lophogaster , Camacea , Isopoda, and Amplii- 
poda , these 5 forming a nearly continuous ascending row, whereas the 
2 remaining, Becapoda and Squillacea , are divergent branches, taking 
their origin near the Euphausiacea. He introduces a new term, 
“ cormopods,’’ for th<3 maxillipeds or gnathopods and thoracic feet or 
periopods altogether, and ho excludes the first pair of antennae (anten- 
nulae) from the number of typically homologous extremities. He also 
reviews the various modifications and appendages of those extremities, 
and compares the whole external structure of his seven orders of Mala- 
costraca from a phylogenetic point of view, urging more particularly the 
relations of the Isopoda to the Mysidacea , and regarding the family 
Tanaidce, especially the genus Apseudes , as a connecting point between 
them. Finally, he gives a short diagnostic description of each Order. 
The plates contain the first cormopod, and first and second maxilla of 
Nebalia with representatives of the other Orders for comparison, besides 
some other particulars. Morph. JB. viii. pp. 485-579, pis. xxi.-xxiv. 
M. Hartog comes to the conclusion that the caudal furca of the Cope- 
pods, etc., is an outgrowth of the last segment, and not strictly com- 
parable to the limbs, and that the telson of the higher Crustacea is 
equivalent to the last segment of the Nauplius stage, together with a 
greatly developed post-anal portion, composed of the supra-anal plate and 
the adnate furcal processes. Rep. Brit. Ass. 1882 [1883], p. 575, woodcut. 
Packard gives a morphological comparison of the lateral appendages 
of the Crustacea, starting from the Phyllopoda , and including also the Tri- 
bolites and Limulus, with numerous woodcuts ; Am. Nat. xvi. pp. 785-799. 
He also proposes the term “gonopoda” for the basal abdominal feet 
of male Decapoda, used as accessory reproductive organs, and “ cerco- 
poda” for the jointed anal appendages of Apus ; 1. c. p. 677.
