Referred Specimens in David (1943:59) : From LACM (CIT) locality 382, Santa Monica Mountains, lower 
Modelo Formation, Late Miocene, Los Angeles County; LACM (CIT) 10150, left and right counter¬ 
parts; 10151, left and right counterparts. 
From LACM (CIT) locality 380, Santa Monica Mountains, lower Modelo Formation, Late Miocene, Los 
Angeles County; 14 slabs (several with more than one specimen), LACM (CIT) 10180-10193, all 
counterparts with some with both right and left and others uncatalogued. Gonostomatidae. 
Holotype and Referred sp ecimens of t/?. vanclevi Jordan and Gilbert reident ifed as t Cyclothone cf. C solitu¬ 
dinis (Jordan) bv David (1943:59) : From Bairdstown (=E1 Sereno neighborhood of east Los 
Angeles), Monterey Formation, Late Miocene, Los Angeles County; holotype, SU 23, left counter¬ 
part, whereabouts unknown. 
From Alhambra, formation not stated, Miocene, Los Angeles County; referred specimen in Jordan 
(1919:8), SU 721, whereabouts unknown. 
Remarks : David (1943:59) included both fit solitudinis Jordan and ff?. vanclevi Jordan and Gilbert in 
f Cyclothone cf. G solitudinis , but we believe this is taxonomically improper because she did not recog¬ 
nize f C solitudinis as a valid species. Thus, we include fff. vanclevi in the synonymy of f Cyclothone cf. 
C solitudinis , but not f/f. solitudinis (see above entry).
