162 Rev. 8. Graham Brade-Birks on Myriapoda., 
p. 67, and in two papers in this series (Brade-Birks, Mar. 
1919 and 1919 d), it will be seen that the name at the head 
of this paragraph has priority, and that the spelling of the 
generic name is as there shown, 
Blaniulus guttulatus (Bose, 1792). 
The writer is in agreement with Chamberlin in his use of 
this name, but Zulus pulchellus, Leach, 1814, is a synonym. 
Nopoiulus minutus (Brandt, 1841) = Nopoiulus hocha 
(Gervais, 1847) = Nopotulus venustus (Meinert, 1868). 
Under the name Nopotulus pulchellus (Leach) it is evident 
that Chamberlin refers to the form called WV. kocht (Gervais) 
in the eighteenth paper in this series (Brade-Birks, Oct. 1919), 
but Julus pulchellus, Leach, 1814, has been shown to be 
synonymous with Julus guttulatus, Bose, 1792 ; and, though 
the name Julus pulchellus, C. L. Koch, 1838, has been used 
for the animal of which we are now speaking, that name, 
being preoccupied by Leach’s use of it, cannot stand here. 
We fell back upon the name kochi (Lulus kochii, Gervais, 
1847), but, accepting Chamberlin’s synonymy, we must adopt 
an earlier name, and call the animal Nopotulus minutus 
(Brandt) (ulus minutus, Brandt, 1841, Recueil. p. 89). 
FURTHER CONSIDERATIONS. 
Brélemann (1921), giving a diagnostic key, expressly 
mentions the family Blaniulide in his title. As far back as 
1847 C. L. Koch (Syst. d. Myr. p. 48) speaks of “ Blani- 
uliden,” and as this name antedates even the genus Jsobates, 
Menge, 1851, the present writer feels that the name Blani- 
ulide is to be preferred to Isobatidee, which is used by Cham- 
berlin (1921). As Chamberlin says, “The use of Protoiulidee 
for this family is inadmissible both because it is antedated by 
the names Isobatidee and Blaniulidze and also because it is 
not based upon an included genus.” 
New genera are established by Brélemann (1921), and as 
British forms fall into three of them, a list of the species thus 
affected is appended :— 
Choneiulus palmatus (Némec). 
Blaniulus palmatus, Némec, 1895, Véstnik kral. ceské spolec- 
nosti nauk, ‘rida math-prirodovédecka (p. 5 of reprint). 
Archiboreotulus pallidus (mili).
