Mr. Templeton’s Description 
My friend Mr. Patterson informs me that, when alive, the pul- 
sations in the tail were extremely visible, and amounted to 122 in 
a minute. He refers the specimen to a figure published by Mr. 
Thompson, of Cork, in his Zoological Researches, and remarks 
that he has no doubt of their identity. With this opinion I cannot 
concur, if the representation given by Mr. Thompson be correct, 
which I have no doubt it is. In this latter ( Zoea Thompsoni), the 
body is proportionally much longer, the processes in length much 
shorter, the eyes differently disposed, and the tail, or abdomen, 
shorter, narrower, and with processes, no trace of which appear 
in the above. I have therefore, as it does not appear to agree 
either with Zoea pelagiea, or Z. clavata, no hesitation in consi- 
dering it a new species, and confer on it, with much gratification, 
the name of the discoverer.* 
The genus Cyclops of Muller at present includes a number of 
species with characters sufficiently decided to warrant their being 
formed into subgenera. Dr. Leach long since separated Calanus. 
In a paper I had lately the honour to present to this Society, I 
detailed the characters of another, being the genus, Sapphirina, 
Thompson: Anomalocer a Patter son'll forms a third, and two yet 
remain clearly distinguished from the other numerous species asso- 
ciated with them in the genus. Attending only to the external forms, 
since our knowledge of their minute structure is still too limited 
to be used with effect in assigning their place with precision, we 
may arrange them in somewhat of the following manner : — 
Cyclops, Auct. 
Antennae long ; annuli of the body suddenly diminishing in 
breadth, forming a tail. 
Eye single, pedunculate ; inferior antenna with a radical 
branch. 
Anomalocer a. . . .Type, A. Patter sonii. 
Eye deeply immersed in the head. 
Superior antennae moderately long. Inferior rather long. 
* I have again to express my regret that the specimen I have had the good 
fortune to examine had not been preserved in spirits, as the degree to which desi- 
eation bad been carried leaves still some doubts in my mind as to the exact form 
of the joints in some parts ; but this, I hope, will not long obscure the history of 
this genus, as I am aware my friend Mr. Westwood, the indefatigable Secretary 
of the Entomological Society, possesses some beautiful specimens preserved in a 
proper manner, and whose size is such as to admit of more minute and careful 
examination, [,2’oea Gigas, Westw. in Philosoph. Trans. 1835, pi. 4, fig. A.
