On Two Strongylata from Swine in the Pacific. 683 
Incisors a little larger than in lateralis, the whole row 
10 mm. in length, about as in hackett?, as compared with 
about 9 mm. in lateral’s. Secator also slightly larger than in 
lateralis, much smaller than in hackett?. 
Dimensions of the type (measured on the remade skin) :— 
Head and body 500 mm.; tail (imperfect) ; hind foot 136; 
ear 43. 
Skull: greatest length 94; condylo-basal length 90; 
zygomatic breadth 48 ; nasals 39 x 14; palatal foramina 7°7. 
Length of 7 4:5, of p* 6°9. Combined length of ms!3 
(unworn) 19. 
(Specimen with p* wholly and p’ partly below the bone.) 
flab. Pearson’s Isles, Investigator Group, S. Australia. 
Type. Immature male. B.M. no, 22.4.15.1. Collected 
25th November, 1920, and presented by Prof. F. Wood 
Junes. 
While the size and general appearance of this Petrogale are 
most like those of P. lateralis, the length of the palatal 
foramina, the comparatively large incisors, the coloration of 
the tail, and, most of all, the characters of the bull all 
indicate a relationship to the Mondrain Island species. 
The Museum is much indebted to Prof. Wood Jones for 
this interesting specimen, all the more that the maritime 
difficulties of getting to the islands are such as to deter any 
mere casual tourists. 
LXXXVIIL.—A Preliminary Note on Two Strongylaia from 
Swine in the Pacijic. By Cuayton LANE. 
CoLLecteD by Dr. F. W. O’Connor, and received through 
his courteous generosity, the nematodes here reported upon 
appear to belong to two new species whose interesting 
affinities will be more fully dealt with subsequently. 
Globovephalus connorfilii, sp. n. 
Stoutish, short, bursate nematodes; the oral aperture 
unarmed and dorso-subterminal; the oral capsule not globular, 
but elongate antero-posteriorly, and provided with a pair of 
rudimentary, basal, subventral teeth projecting into the oral 
cavity which conforms to the shape and size of the capsule. 
This latter has two transverse thickenings—one close and 
parallel to the almost circular oral aperture, Oe ae at the
