the latter is a noun substantive of neuter gender ; as Ortho-sioma, Dvplo-doma, 
Aca/nthosoma." 
My original objection was meant to include a class of words like Phanerotonia 
dentatum, Pentatoma bipuactatum, nigricome, vernale, Tapinoma erraticum, and 
80 forth. The list could easily be extended, but these examples will suffice. It is 
plain that Phanerotoma, Pentatoma, &c., cannot be excused upon the ground of 
their ending with a neuter substantive, and consequently that their adjectives are 
made neuter at the expense of the ordinary rules of gender. 
2. " Is there any reason why a compound noun substantive may not be taken 
ibr the name of a genus, when a simple noun substantive may ? If Haryna will 
do, why not Chalcarma? If Phasyyia, why not Neophasma ?" — I see no objection 
to either word. 
It appears that all zoological names are capable of being referred to one or 
other of the two following classes. 
A. SUBSTANTIVES, which may be, as to their form, either simple or compound • 
and as to their meaning, either literal or figurative. Ex. gr. 
a. Simple or compound substantives taken literally : — 
Ursus Bear. Tragelaphus Goat-deer. 
Cynomyia Dog-fly. Psammoaaurus Sand-lizard. 
Haliaetus Sea-eagle. Lampyris Glow-worm, 
h. Simple or compound substantives taken figuratively : — 
Ctenidium little comb. Scymnus a whelp. 
Micrornix little bird. Sphasridium a little ball. 
Helluo glutton. Mormolyce a hobgoblin. 
Nautilus sailor. Phasma an apparition. 
Machaon ~\ Neophasma a new Phasma. 
Artaxerxes > ...proper names. Harma a chariot. 
Feronia J Ghalcharma a brazen chariot. 
B. ADJECTIVES, which express only some attribute of their subject (i. e. the 
creature designated) and never the whole of the subject, — which if they did, they 
would oease to be adjectives. Ex. gr. 
Atomogaster Without abdominal incisions, 
Endocephalua Having the head turned inwards. 
Platycephala Broad-headed. 
Lepidoptera Having scaly wings. 
Qnadrumana Four-handed. 
Tetratoma Quadripartite.
