 incised, similar in form; plates arranged 0, 1, 1, 4, those of each lateris 

 situated, one adjacent to third lobe, one near middle, two at cephalic end, 

 these plates much larger than others; oraceratubae situated one on me- 

 son, one in each second incisura, one in each third incisura, one between 

 lobelets of each third pair of lobes, two cephalad of first plate of each 

 lateris, one cephalad of second; spiracerores wanting. Ischnaspis

SPECIES OF NIVEASPIS 



Pygidiurn with median pair of lobes hardly projecting, margin entire, 

 caudal end truncated, angles rounded; each second lobe with margin 

 more oblique, hardly projecting; plates wanting, but with spine-like 

 projections, these projections in median and second incisurae and 

 cephalad of third pair of lobes; preabdomen with lateral margins of 

 segments straight, but with strong finger-like process near each caudo- 



lateral angle. Lepiodsaphes argentata Ckll. Brazil, Mexico

 ly projecting; second pair of lobes large, short and broad, much 

 broader than long, entire, distal margin convex, each six or eight times 

 as broad as median lobe; plates wanting; oraceratuba in each second 

 incisura, another cephalad of each second lobe, three on each lateris 

 cephalad of second lobe, equidistant from each other and oraceratuba 

 adjacent to this lobe; each lateris apparently with densariae in 

 which oraceratubae open; mesospiracerores 0-1. Fernaldella indentata 

 Green. Australia. indentata Green. 



SPECIES OF MASKELLANNA 



Pygidium with median pair of lobes minute, narrow, rounded, entire, 

 constricted on proximal portion, very distant; second pair of lobes mi- 

 nute, subequal in size to median and similar in form, distant from 

 median; plates wanting; altaceratubae arranged 1, 1, 2, 2, 1, one in 

 median incisura; setae minute; lateres with slight projections near 

 oraceratubae of altaceratubae, otherwise entire; dorsal oraceratubae 

 numerous, minute, promiscuously arranged; body of adult female 

 strongly chitinized, no differentiation between pygidium and other 

 parts. Mytilaspis (Ferneldella) beyeriae Green. Australia on Bey- 

 eria. beycriae Green. 



SPECIES OF PHAULOMYTILIUS 



Pygidium without lobes or plates; margin irregularly crenulate; with 

 four small, conical, widely separated, spine-like projections arising 

 from surface of pygidium; large oraceratuba located on each side of
