This species varies more than any other in its armature and in the 

 degree of convergence of tlie parietals, facts whicli lend weight to the 

 supposition that it is the central species about which the others are 

 grouped. The specimens examined are from San Francisco and show 

 the following" variations: 



Individual rariations in Primofspiria mystinus.

This species is only provisionally placed here. We have not exam- 

 ined it, but Mr. F. C. Test informs us that the parietals are united, and 

 that the parietal ridges end in minute spines. In the last point this 

 species agrees with the genus Acutomentum, but the absence of i)ostocu- 

 lar and the occasional absence of supraocular and tympanic spines 

 unite this variable species with the variable PrimoHpina. 



V. Genus SEBASTOSOMUS (Gill).

This genus differs from all others in the fact that no cranial spines ,. 

 are developed. 1 1
