Form. ^ Log. Upper Cretaceous : Sendenhorst, Westphalia. 
jN^ot represented in the Collection. 
The following specimens, apparently referable to the genus 
Osineroides^ are not specifically determined :— 
P. 6850. Part of opercular and abdominal region of very large 
specimen, with remains of a pelvic fin unusually far 
forwards; Chalk, Willingdon, Eastbourne. 
Presented hy Miss Hememann, 1893. 
39433. Eemarkably elongated head and opercular apparatus, very 
imperfectly preserved, with some anterior vertebrae; 
English Chalk. Boiuerhanlc Coll. 
P. 5679. Opercular, branchiostegal apparatus, &c.; Lower Chalk, 
Kent. Harford Coll. 
49752. Scattered remains of head showing gular plate; Chalk, 
Amberley, Sussex. Capron Coll. 
P. 8949. Portion of jaws and opercular apparatus, remarkably 
smooth, with large gular plate; Gault, Folkestone. 
Purchased, 1898. 
P. 9005. Imperfect head and trunk of the form bearing the MS. 
name Osmeroides vinarensis (A. Eritsch, Archiv naturw. 
Landesdurchf. Bohmen, vol. v. no. 2, 1883, p. 88); 
Senonian (Iserschichten), Vinary, Bohemia. 
Purchased, 1899. 
P. 9188. Fish nearly 0*3 in length, in the counterpart halves of a 
nodule; Upper Cretaceous, Barra do Jardim, Serra de 
Araripe, Province of Ceara, Brazil. The head is too 
imperfect to determine the genus, and the squamation is 
more strongly ornamented by linear markings than usual 
in Osmeroides. Purchased, 1900. 
The following specimens seem to represent a genus related to 
Osmeroides, with wider gape and thinner and larger scales, but are 
too incomplete for precise determination :— 
39432. Imperfect head and abdominal region, about 0*5 in length 
and 0-12 in depth, showing the long, straight maxilla.
